Hmm. I am sad that this change has broken somebody's existing workflow.
OTOH, I'm not convinced that workflow wasn't a little crazy to begin
with, depending on this undocumented munging.

How about:
$ cat .git/hooks/prepare-commit-msg
#!/bin/sh
git diff --cached >>"$1"
$ cat .git/hooks/commit-msg
#!/bin/sh
sed -i '/^diff --git/Q' "$1"
which is more or less the original behavior. The only downside I see is
that "--no-verify" will turn off the commit-msg hook, but not the
prepare-commit-msg hook.
