No, I don't think there is currently a better way.
If you do go the file watch route, make sure you put one on HEAD, too
(to catch the case of checking out a different branch, as opposed to
updating it with a new commit). I use:
gitdir=$(git rev-parse --git-dir)
# We need delete_self to pick up changes to HEAD (since it gets renamed
# over), and "move" to pick up changes in the refs directories.
inotifywait -qq -t 60 -e delete_self -e move -r "$gitdir/HEAD" "$gitdir/refs"
in a script that I use for automatically running tests against the
current commit. (if you are doing something similar, I also recommend
https://github.com/mhagger/git-test for avoiding re-running against the
same commits repeatedly).
