feature request: handle broken From headers that include signature

feature request: handle broken From headers that include signature

[Greg Stark]

There's a particular configuration error some people make that causes their
mailer to use their .signature file as their mail signature.  That is, use
their 5+ line signature in the From header of their mail messages.

Gnus doesn't simplify the header in any way when this happens, it does
something like this:

  +[  26: --------------------] Cockatrices, Basilisks and other Gargoyle Manufacturers

From: ------------------------------------------------------------------------------ <name-witheld@MIT.EDU>

Obviously the best it can do is some kind of heuristic, but it seems like Gnus
should be able to tell at least sometimes that it's not looking at the
author's name.  I would need to see a few more examples before I even had a
decent suggestion for what the heuristic should be.
