Carl Worth 97b5f81533 notmuch.el: Don't hide long signatures.
Chances are, a signature above a certain threshold isn't just a
signature, (for example, it could be an encrypted messages tacked onto
the end of the file, or could be any sort of PS.)

We add a new variable, notmuch-show-signature-lines-max that can be
used to configure the threshold, (set to 6 by default for now).
