Interesting. So those who really really hate cover letters can set
the configuration explicitly to 'off' and giving an --interdiff
option would still have the sanity check kick in. Makes sense.

I was about to make the follwoing:
Swap these two. Arrange things we are going to create to be
removed at end, and then start creating them. That way, we will
clean them up even if we fail after creating some but before the
end of the command.
but this one is littered with exiting breakage, so I'll let it pass.
Somebody will later go in and fix them all (#leftoverbits).

Isn't the name of the cover letter file always cover-letter.patch
unless you configure a custom --suffix (which is not the case here)?

OK.

Looking good.
