mcom: check if a draft was found when invoking `mcom -r`
Without this patch `mcom -r` would invoke $EDITOR on a directory if the
maildir did not contain any drafts. To prevent this from happening,
check if a draft was found before performing any further processing. If
not, terminate mcom with an error message.

A patch file from https://github.com/leahneukirchen/mblaze/pull/169.patch is attached
