I also find the following alias useful to find the version number a
commit is first merged in:

vc = "!vc() { for i in `git tag --contains \"$@\" | grep '^v'`; do echo \"$(git log -1 --pretty='%ct' $i) $i\"; done | sort -n | head -n1 | sed 's/^[0-9]* //g'; }; vc"

Its a bit slow and hacky and there's probably better ways, but it picks
the tag a bit more reliably than "git describe --contains". Maybe that
could be wrapped in a script that generates a Stable tag automatically
from a Fixes tag for when the patch is suitable for stable.

Cheers
James
