Except that "template" is already taken. Someone uses it and some may
even got used to "template" having that meaning.

Not really. It will be run even if the template (the one Git have
already) is not used.

It really looks a bit complicated. If at all, how about running that
"pre-editor" hook with information about where the message comes from?

I.e. if the message comes from a template:

    preedit-commit-msg .git/COMMIT_MSG template

or, for a message coming from commit:

    preedit-commit-msg .git/COMMIT_MSG commit 0123456789abdef

or, for a message coming from a file

    preedit-commit-msg .git/COMMIT_MSG file user/path/to/file

and finally, for a new message:

    preedit-commit-msg .git/COMMIT_MSG

?
