This is awesome. thanks!

I really like the new error message specific to the situation when
the user does not edit the template (as we discussed).

Your patches apply cleanly to maint b8939b2b3abaa.

I tested the patches and they work as expected. When I use
`git commit --template FILE` but do not edit the message in my editor,
I get

	Aborting commit; you did not edit the message.

Nice.

Only thing I'd add is a change to the git-commit(1) manpage.

* I prefer pragmatically explaining what will happen when the user
  uses --template but does not edit the message because it is more
  direct and terse (than "filling in a form").
* The below applies cleanly to maint as of today.
* I don't know the kosher procedure to add this commit to your patch
  series for further review, so hopefully this works.
* I'm not sure if the "Helped-by:" lines are kosher, I'm happy to
  remove them if not.

Subject: [PATCH] git-commit.txt: clarify -t requires editing message

Make it clear that, when using commit --template, the message *must* be
changed or the commit will be aborted.

I wrapped the text at 77 characters because that was the longest
line in the file (according to wc -L).

I used ":set noet nosta ts=8 sw=8 tw=77" in Vim.
