Below there is preliminary (hence RFC) committag support for gitweb,
based on the idea introduced by Sham Chukoury to gitweb-xmms2.
The code has all the possible committags I could think of enabled;
not all are tested, though. This includes existing commitsha tag
support (full sha links to commit view, is sha is sha of commit),
mantis bug and feature tags from gitweb-xmms2 (there is no release
committag of gitweb-xmms2, but it should be fairly easy to add it),
bugzilla committag for the Linux kernel, plain text URL committag
(probably doesn't work that well, marking as links examples, and
sometimes protocol specification), and Message-Id committag via
GMane git mailing list (and not only) archive -- not tested.
Comments? Discussion?
This patch is rather not for inclusion; it is not in format-patch form.
P.S. I've corrected git_get_type for comparison
git_get_type($hash) eq "commit"
to work without Perl syntax errors.
