Trailing newlines are stripped from any attachments to PRs. This is a problem

commonly manifested by distinfo updates, where the file ends up without a
newline.  Newer versions of GNU patch also choke on such patches.

There is probably a more elegant solution than this, but given that GNATS
is not going to be with us for too long, we can rely on the behaviour of tools
to ignore any trailing newlines if they are added incorrectly [patch, shar].

Anyone who can show that adding extra newlines to attachments causes breakage
is welcome to comment.
