I think this series would be useful.  I've occasionally included the
"squash!" line in my commit even after I've edited the rest of the
commit message.  It's not super frequent, but it is a hassle to have to
delete it, and it does happen occasionally.  Usually I catch it before I
send out the series for review.

I can see the argument that this makes it a little harder for mechanical
processing across versions, but I suspect most of that looks something
like "sed -i -e '/^squash! /d' COMMIT_EDITMSG" and it probably won't be
affected.  We do make occasional slightly incompatible changes across
versions in order to improve user experience, and I think a lot of folks
who use squash commits will find this a pleasant improvement.
