Small change. Still need to load MERGE_MSG and SQUASH_MSG
if there's no prepare-commit-msg hook. We now process the hook

This patch looks reasonable. My only comment is maybe we want
to delete PREPARE_COMMIT_MSG file when we "exit 1" when the hook
has declined.
Good catch. I've added that to the latest patch.

Can you please try to put this onto my current git-gui tree?
I don't have the base 10d8a44 object so I can't 3-way merge
this in, and the patch doesn't apply cleanly anymore.
Absolutely. Here it is:
Add support to git-gui for calling out to the prepare-commit-msg hook.
