This is actually a few different changes to request-pull,
making it slightly smarter:
1) Minor cleanup of revision->base variable names, making it
follow the head/headrev naming convention that is already
in use.
2) Compute the merge-base between the two revisions upfront
and reuse that selected merge-base to create the diffstat.
3) Refuse to generate a pull request for branches that have no
existing relationship. These aren't very common and would mess
up our diffstat generation.
4) Disable the PAGER when running shortlog and diff, as these
would otherwise activate the pager for each command when
git-request-pull is run on a tty. Instead users can get the
entire output paged (if desired) using `git -p request-pull`.
5) Use shortlog rather than `git log | git shortlog` now that
recent shortlog versions are able to run the revision listing
internally.
6) Attempt to resolve the input URL using the user's configured
remotes. This is useful if the URL you want the recipient to
see is also the one you used to push your changes. If not a
config-file remote could easily be setup for the public URL
and request-pull could be passed that name instead.
7) Automatically guess and include the remote branch name in the
body of the message. We list the branch name immediately after
the URL, making it easy for the recipient to copy and paste
the entire line onto a `git pull` command line. Rumor has it
Linus likes this format, for exactly that reason.
If multiple branches at the remote match $headrev we take the
first one returned by peek-remote and assume it is suitable.
If no branches are available we warn the user about the problem,
but insert a static string that is not a valid branch name
and would be obvious to anyone reading the message as being
totally incorrect. This allows users to still generate a
template message without network access (for example) and
hand-correct the bits that cannot be verified.

//////////////////////////////////////////////////////////////// GIT - the stupid content tracker //////////////////////////////////////////////////////////////// "git" can mean anything, depending on your mood. - random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant. - stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang. - "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room. - "goddamn idiotic truckload of sh*t": when it breaks Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals. Git is an Open Source project covered by the GNU General Public License. It was originally written by Linus Torvalds with help of a group of hackers around the net. It is currently maintained by Junio C Hamano. Please read the file INSTALL for installation instructions. See Documentation/tutorial.txt to get started, then see Documentation/everyday.txt for a useful minimum set of commands, and "man git-commandname" for documentation of each command. CVS users may also want to read Documentation/cvs-migration.txt. Many Git online resources are accessible from http://git.or.cz/ including full documentation and Git related tools. The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org. To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at http://marc.theaimsgroup.com/?l=git and other archival sites. The messages titled "A note from the maintainer", "What's in git.git (stable)" and "What's cooking in git.git (topics)" and the discussion following them on the mailing list give a good reference for project status, development direction and remaining tasks.
