Option q implies d, i.e., it marks any undecided hunks towards the
bottom of the hunk array as skipped. This is unnecessary; later code
treats undecided and skipped hunks the same: The only functions that
use UNDECIDED_HUNK and SKIP_HUNK are patch_update_file() itself (but
not after its big for loop) and its helpers get_first_undecided() and
display_hunks().

Options a and d stage and unstage all undecided hunks towards the bottom
of the array of hunks, respectively, and then roll over to the very

The options y, n, and e mark the current hunk as decided. If there's
another undecided hunk towards the bottom of the hunk array they go
there. If there isn't, but there is another undecided hunk towards the
top then they go to the very first hunk, no matter if it has already
been decided on.
The option j does basically the same move. Technically it is not
allowed if there's no undecided hunk towards the bottom, but the
variable "permitted" is never reset, so this permission is retained
from the very first hunk. That may a bug, but this behavior is at
least consistent with y, n, and e and arguably more useful than
refusing to move.
Improve the roll-over behavior of these four options by moving to the
first undecided hunk instead of hunk 1, consistent with what they do
when not rolling over.
Also adjust the error message for j, as it will only be shown if
there's no other undecided hunk in either direction.

If, when the user edits a hunk, they change deletion lines into
context lines or vice versa, then the number of hunks that the edited
hunk can be split into may differ from the unedited hunk. This means
that so we should recalculate `hunk->splittable_into` after the hunk
has been edited. In practice users are unlikely to hit this bug as it
is doubtful that a user who has edited a hunk will split it afterwards.

When a hunk is split, each of the new hunks inherits whether it is
selected or not from the original hunk. If a selected hunk is split
all of the new hunks are marked as "selected" and the user is only
prompted with the first of the split hunks. The user is not asked
whether or not they wish to select the rest of the new hunks. This
means that if they wish to deselect any of the new hunks apart from
the first one they have to navigate back to the hunk they want to
deselect before they can deselect it. This is unfortunate as the user
is presumably splitting the original hunk because they only want to
select some sub-set of it.
Instead mark all the new hunks as "undecided" so that the user is
prompted whether they wish to select each one in turn. In the case
where the user only wants to change the selection of the first of
the split hunks they will now have to do more work re-selecting the
remaining split hunks. However, changing the selection of any of the
other newly created hunks is now much simpler as the user no-longer has
to navigate back to them in order to change their selected state.

The old perl git-add--interactive.perl script used the color.diff config
option to decide whether to color diffs (and if not set, it fell back to
the value of color.ui via git-config's --get-colorbool option). When we
switched to the builtin version, this was lost: we respect only
color.ui. So for example:
git -c color.diff=false add -p
would color the diff, even when it should not.
The culprit is this line in add-interactive.c's parse_diff():
if (want_color_fd(1, -1))
That "-1" means "no config has been set", which causes it to fall back
to the color.ui setting. We should instead be passing the value of
color.diff. But the problem is that we never even parse that config
option!
Instead the builtin interactive code parses only the value of
color.interactive, which is used for prompts and other messages. One
could perhaps argue that this should cover interactive diff coloring,
too, but historically it did not. The perl script treated
color.interactive and color.diff separately. So we should grab the
values for both, keeping separate fields in our add_i_state variable,
rather than a single use_color field.
We also load individual color slots (e.g., color.interactive.prompt),
leaving them as the empty string when color is disabled. This happens
via the init_color() helper in add-interactive, which checks that
use_color field. Now that there are two such fields, we need to pass the
appropriate one for each color.
The colors are mostly easy to divide up; color.interactive.* follows
color.interactive, and color.diff.* follows color.diff. But the "reset"
color is tricky. It is used for both types of coloring, but the two can
be configured independently. So we introduce two separate reset colors,
and use each in the appropriate spot.
There are two new tests. The first enables interactive prompt colors but
disables color.diff. We should see a colored prompt but not a colored
diff, showing that we are now respecting color.diff (and not
color.interactive or color.ui).
The second does the opposite. We disable color.interactive but turn on
color.diff with a custom fragment color. When we split a hunk, the
interactive code has to re-color the hunk header, which lets us check
that we correctly loaded the color.diff.frag config based on color.diff,
not color.interactive.

Make the print command trigger the pager when invoked using a capital

Note that if the PAGER ends unexpectedly before we've been able to send
the payload, perhaps because the user is not interested in the whole
thing, we might receive a SIGPIPE, which would abruptly and unexpectedly
terminate the interactive session for the user.
Therefore, we need to ignore a possible SIGPIPE signal. Add a test for
this, in addition to the test for normal operation.
For the SIGPIPE test, we need to make sure that we completely fill the
operating system's buffer, otherwise we might not trigger the SIGPIPE
signal. The normal size of this buffer in different OSs varies from a
few KBs to 1MB. Use a payload large enough to guarantee that we exceed
this limit.

After the user has edited a hunk the number of lines in the pre- and
post- image lines is recounted the hunk header can be updated before
passing the hunk to "git apply". The recounting code correctly handles
empty context lines where the leading ' ' is omitted by treating '\n'
and '\r' as context lines.
Update this code to use normalize_marker() so that the handling of empty
context lines is consistent with the rest of the hunk parsing
code. There is a small change in behavior as normalize_marker() only
treats "\r\n" as an empty context line rather than any line starting
with '\r'. This should not matter in practice as Macs have used Unix
line endings since MacOs 10 was released in 2001 and if it transpires
that someone is still using an earlier version of MacOs where lines end
with '\r' then we will need to change the handling of '\r' in
normalize_marker() anyway.

When "add -p" parses diffs, it looks for context lines starting with a
single space. But when diff.suppressBlankEmpty is in effect, an empty
context line will omit the space, giving us a true empty line. This
confuses the parser, which is unable to split based on such a line.
It's tempting to say that we should just make sure that we generate a
diff without that option. However, although we do not parse hunks that
the user has manually edited with parse_diff() we do allow the user
to split such hunks. As POSIX calls the decision of whether to print the
space here "implementation-defined" we need to handle edited hunks where
empty context lines omit the space.
So let's handle both cases: a context line either starts with a space or
consists of a totally empty line by normalizing the first character to a
space when we parse them. Normalizing the first character rather than
changing the code to check for a space or newline will hopefully future
proof against introducing similar bugs if the code is changed.

Use of the `the_repository` variable is deprecated nowadays, and we
slowly but steadily convert the codebase to not use it anymore. Instead,
callers should be passing down the repository to work on via parameters.
It is hard though to prove that a given code unit does not use this
variable anymore. The most trivial case, merely demonstrating that there
is no direct use of `the_repository`, is already a bit of a pain during
code reviews as the reviewer needs to manually verify claims made by the
patch author. The bigger problem though is that we have many interfaces
that implicitly rely on `the_repository`.
Introduce a new `USE_THE_REPOSITORY_VARIABLE` macro that allows code
units to opt into usage of `the_repository`. The intent of this macro is
to demonstrate that a certain code unit does not use this variable
anymore, and to keep it from new dependencies on it in future changes,
be it explicit or implicit
For now, the macro only guards `the_repository` itself as well as
`the_hash_algo`. There are many more known interfaces where we have an
implicit dependency on `the_repository`, but those are not guarded at
the current point in time. Over time though, we should start to add
guards as required (or even better, just remove them).
Define the macro as required in our code units. As expected, most of our
code still relies on the global variable. Nearly all of our builtins
rely on the variable as there is no way yet to pass `the_repository` to
their entry point. For now, declare the macro in "biultin.h" to keep the
required changes at least a little bit more contained.

In a "git add -p" session, especially when we are not using the

and then just do the 'q' thing (i.e. quit the session), ignoring

If 'q' and 'a' are next to each other on the user's keyboard, there
is a plausible chance that we see 'qa' when the user who wanted to
say 'a' fat-fingered and we ended up doing the 'q' thing instead.
As we didn't think of a good reason during the review discussion why
we want to accept excess letters only to ignore them, it appears to
be a safe change to simply reject input that is longer than just one
byte.
The two exceptions are the 'g' command that takes a hunk number, and
the '/' command that takes a regular expression. They have to be
accompanied by their operands (this makes me wonder how users who
set the interactive.singlekey configuration feed these operands---it
turns out that we notice there is no operand and give them another
chance to type the operand separately, without using single key
input this time), so we accept a string that is more than one byte
long.
Keep the "use only the first byte, downcased" behaviour when we ask
yes/no question, though. Neither on Qwerty or on Dvorak, 'y' and

format strings, or strbuf_addch() for strbuf_addstr(). The type system
and printf-attribute give the compiler enough information to make sure
our formats and variable changes all match (especially important for
cases where the format string is defined far away from its use, like
prepare_to_commit() in commit.c).

As part of our transition to multi-byte comment characters, let's take a
NUL-terminated string pointer for strbuf_commented_addf() rather than a
single character.
All of the callers have to be adjusted, but they can just pass
comment_line_str rather than comment_line_char.
Note that we rely on strbuf_add_commented_lines() under the hood, so
we'll cheat a bit to squeeze our string into a single character (for now
the two are equivalent, and we'll address this TODO in the next patch).

Currently, (restore, checkout, reset) commands correctly take '@' as a
synonym for 'HEAD'. However, in patch mode different prompts/messages
are given on command line due to patch mode machinery not considering
'@' to be a synonym for 'HEAD' due to literal string comparison with
the word 'HEAD', and therefore assigning patch_mode_($command)_nothead
and triggering reverse mode (-R in diff-index). The NEEDSWORK comment
suggested comparing commit objects to get around this. However, doing
so would also take a non-checked out branch pointing to the same commit
as HEAD, as HEAD. This would cause confusion to the user.
Therefore, after parsing '@', replace it with 'HEAD' as reasonably
early as possible. This also solves another problem of disparity
between 'git checkout HEAD' and 'git checkout @' (latter detaches at
the HEAD commit and the former does not).
Trade-offs:
- Some of the errors would show the revision argument as 'HEAD' when
given '@'. This should be fine, as most users who probably use '@'
would be aware that it is a shortcut for 'HEAD' and most probably
used to use 'HEAD'. There is also relevant documentation in
'gitrevisions' manpage about '@' being the shortcut for 'HEAD'. Also,
the simplicity of the solution far outweighs this cost.
- Consider '@' as a shortcut for 'HEAD' even if 'refs/heads/@' exists
at a different commit. Naming a branch '@' is an obvious foot-gun and
many existing commands already take '@' for 'HEAD' even if
'refs/heads/@' exists at a different commit or does not exist at all
(e.g. 'git log @', 'git push origin @' etc.). Therefore this is an
existing assumption and should not be a problem.

Each of these were checked with
gcc -E -I. ${SOURCE_FILE} | grep ${HEADER_FILE}
to ensure that removing the direct inclusion of the header actually
resulted in that header no longer being included at all (i.e. that
no other header pulled it in transitively).
...except for a few cases where we verified that although the header
was brought in transitively, nothing from it was directly used in
that source file. These cases were:
* builtin/credential-cache.c
* builtin/pull.c
* builtin/send-pack.c

Further shuffling of declarations across header files to streamline
file dependencies.
* cw/compat-util-header-cleanup:
git-compat-util: move alloc macros to git-compat-util.h
treewide: remove unnecessary includes for wrapper.h
kwset: move translation table from ctype
sane-ctype.h: create header for sane-ctype macros
git-compat-util: move wrapper.c funcs to its header
git-compat-util: move strbuf.c funcs to its header
Move functions that are not about pure string manipulation out of
strbuf.[ch]
* cw/strbuf-cleanup:
strbuf: remove global variable
path: move related function to path
object-name: move related functions to object-name
credential-store: move related functions to credential-store file
abspath: move related functions to abspath
strbuf: clarify dependency
strbuf: clarify API boundary
alloc_nr, ALLOC_GROW, and ALLOC_GROW_BY are commonly used macros for
dynamic array allocation. Moving these macros to git-compat-util.h with
the other alloc macros focuses alloc.[ch] to allocation for Git objects
and additionally allows us to remove inclusions to alloc.h from files
that solely used the above macros.

This also made it clear that several .c files depended upon various
things that oidset included, but had omitted the direct #include for
those headers. Add those now.

Since this header showed up in some places besides just #include
statements, update/clean-up/remove those other places as well.
Note that compat/fsmonitor/fsm-path-utils-darwin.c previously got
away with violating the rule that all files must start with an include
of git-compat-util.h (or a short-list of alternate headers that happen
to include it first). This change exposed the violation and caused it
to stop building correctly; fix it by having it include
git-compat-util.h first, as per policy.

For the functions defined in read-cache.c, move their declarations from
cache.h to a new header, read-cache-ll.h. Also move some related inline
functions from cache.h to read-cache.h. The purpose of the
read-cache-ll.h/read-cache.h split is that about 70% of the sites don't
need the inline functions and the extra headers they include.
