Use git hook to re-initialize a subdirectory

I guess that works, although it makes me a bit uncomfortable because
if your script gets interrupted halfway through, your hook could be
left in a permanently disabled state.

Also, do you really mean to exit 0 even if git-commit fails?

Anyway, I'm glad you've found a solution.
