Fix commit-msg hook to allow editing

Browse source 
The old git-commit.sh script allowed the commit-msg hook to not only
prevent a commit from proceding, but also to edit the commit message
on the fly and allow it to proceed. So here we teach builtin-commit
to do the same.

This is based on Wincent's patch, but redone with a clarified logic.
