While it is not *wrong* per-se to say that pulling a rewound/rebased
branch will lead to an unnecessary merge conflict, that is not what
the leading "+" sign to allow non-fast-forward update of remote-tracking
branch is at all.

- "Branches" is a more common way to say "heads" in these days.
- Remote-tracking branches are used a lot more these days and it is
worth mentioning that it is one of the primary side effects of
the command to update them.
- Avoid "X. That means Y." If Y is easier to understand to
readers, just say that upfront.
- Use of explicit refspec to fetch tags does not have much to do
with turning "auto following" on or off. It is a way to fetch
tags that otherwise would not be fetched by auto-following.

This is a convenience wrapper to call tolower on each
character of the string.
This makes config's lowercase() function obsolete, though
note that because we have a strbuf, we are careful to
operate over the whole strbuf, rather than assuming that a
NUL is the end-of-string.
We could continue to offer a pure-string lowercase, but
there would be no callers (in most pure-string cases, we
actually duplicate and lowercase the duplicate, for which we
have the xstrdup_tolower wrapper).

This reverts commit d508e4a8e2,
reversing changes made to e42552135a.
The author of the original topic says he broke the upcoming 2.0
release with something that relates to "synchronization crash
regression" while refusing to give further specifics, so this would
unfortunately be the safest option for the upcoming release.

When core.commentChar is "auto", the comment char starts with '#' as
in default but if it's already in the prepared message, find another
char in a small subset. This should stop surprises because git strips
some lines unexpectedly.
Note that git is not smart enough to recognize '#' as the comment char
in custom templates and convert it if the final comment char is
different. It thinks '#' lines in custom templates as part of the
commit message. So don't use this with custom templates.

The argv_array_detach function (and associated free() function) was
really only useful for transferring ownership of the memory to a "struct
child_process". Now that we have an internal argv_array in that struct,
there are no callers left.

All child_process structs need to point to an argv. For
flexibility, we do not mandate the use of a dynamic
argv_array. However, because the child_process does not own
the memory, this can make memory management with a
separate argv_array difficult.
For example, if a function calls start_command but not
finish_command, the argv memory must persist. The code needs
to arrange to clean up the argv_array separately after
finish_command runs. As a result, some of our code in this
situation just leaks the memory.
To help such cases, this patch adds a built-in argv_array to
the child_process, which gets cleaned up automatically (both
in finish_command and when start_command fails). Callers
may use it if they choose, but can continue to use the raw
argv if they wish.

EXAMPLE
To disable interactive logins, displaying a greeting
instead:
+
$ chsh -s /usr/bin/git-shell
$ mkdir $HOME/git-shell-commands
[...]
The stray "+" has been there ever since the example was added in
v1.8.3-rc0~210^2 (shell: new no-interactive-login command to print a
custom message, 2013-03-09). The "+" sign between paragraphs is
needed in asciidoc to attach extra paragraphs to a list item but here
it is not needed and ends up rendered as a literal "+". Remove it.

By default, Git used to set $LESS to -FRSX if $LESS was not set by
the user. The FRX flags actually make sense for Git (F and X because
sometimes the output Git pipes to less is short, and R because Git
pipes colored output). The S flag (chop long lines), on the other
hand, is not related to Git and is a matter of user preference. Git
should not decide for the user to change LESS's default.
More specifically, the S flag harms users who review untrusted code
within a pager, since a patch looking like:
-old code;
+new good code; [... lots of tabs ...] malicious code;
would appear identical to:
-old code;
+new good code;
Users who prefer the old behavior can still set the $LESS environment
variable to -FRSX explicitly, or set core.pager to 'less -S'.
The documentation in config.txt is made a bit longer to keep both an
example setting the 'S' flag (needed to recover the old behavior)
and an example showing how to unset a flag set by Git.

The original motivation of using the prompt was to confirm to run a
tool on this particular (as opposed to another) path, but the user
can also take the prompt as to confirm to run this (as opposed to
some other) tool. The latter of which of course is irritating for
those who told which exact tool to use, which is the reason why we
are flipping the default.
During the review discussion of the patch, many people (including
the maintainer) missed that a user can find the prompt useful way to
skip running the tool on particular paths. Clarify it by adding a
brief half-sentence to the description.
