Responds to Git post-commit events. It makes sure that any files which
are marked as lockable by git lfs track
are read-only in the working
copy, if not currently locked by the local user.
Where the git lfs post-merge
command, which has a similar purpose,
must examine all files in the working copy, git lfs post-commit
can
limit itself checking only those files which have changed in HEAD
. It
primarily handles newly added lockable files which have not yet been
made read-only.
