Hey all--

I'm running from the head of notmuch development right now, and when i
reply to multipart/signed or multipart/mixed mail in notmuch-emacs, i'm
noticing that the attributed text now has excessive indentation (it did
not when running from the latest release).

to be clear, i'm talking about replies that now look like:

interestingly, the command line still shows the right thing:

  notmuch reply id:$MSGID

has the correct layer of indentation, as does:

  notmuch reply --decrypt id:$MSGID

Does anyone else see this behavior?  If you're using notmuch-emacs, try
replying to this message and looking at the attributed text.
