If you were issuing emails for two branches, and one merged the other,
you would get the same log messages appearing in two separate emails.
e.g. A working repository, where the last push to central was done at
the revision marked "B", after which two branches were developed
further.
* -- B -- 1 -- 1 -- M (branch1)
\ /
2 -- 2 -- 2 (branch2)
Now imagine that branch2 is pushed to the email-generating repository;
an email containing all the "2" revisions would be sent. Now, let's say
branch1 is pushed, the old update hook would run
git-rev-list $newrev ^$baserev
Where $newrev would be "M" and $baserev would be "B". This list
includes all the "2" revisions as well as all the "1" revisions.
This patch addresses this problem by using
git-rev-parse --not --all | git-rev-list --stdin $newrev ^$baserev
To inhibit the display of all revisions that are already in the
repository.

//////////////////////////////////////////////////////////////// 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.
