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

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.

"Pattern to match a line that separates content from signature.
The regexp can (and should) include $ to match the end of the
line, but should not include ^ to match the beginning of the

for indentation at the beginning of the line. But notmuch will
move past the indentation when testing this pattern, (so that the
pattern can still test against the entire line).")
