notmuch.el: Consider an entire line of underscores as a signature separator.

Browse source 
This is the default separator used by mailman, so there's a lot of
clutter in thread displays without this. Also, we not provide a nice
variable to the user (notmuch-show-signature-regexp) for configuring
this.

The regexp can (and should) include $ to match the end of the

for indentation at the beginning of the line. But notmuch will
move past the indentation when testing this pattern, (so that the
