Hi, is the attached patch to MH-E eligible for emacs-28, or should it go
into master?

The patch fixes a problem that happens when forwarding an email that has
a 2-line From line, e.g.,

  From: "Some User"
    <some.user@company.com>
  To: Another User <another.user@another-company.com>
  Subject: 2-line From

Without the fix, the user is presented with a corrupted set of headers,
e.g.,

  From: Mike Kupfer <mkupfer@alum.berkeley.edu>
  To: 
  cc: 
  Fcc: +inbox
  Subject: "Some User"
  X-Mailer: MH-E 8.6+git; nmh 1.7.1; GNU Emacs 28.0.60
  : 2-line From

With the fix, the headers are correct, e.g.,

  From: Mike Kupfer <mkupfer@alum.berkeley.edu>
  To: 
  cc: 
  Fcc: +inbox
  Subject: "Some User": 2-line From
  X-Mailer: MH-E 8.6+git; nmh 1.7.1; GNU Emacs 28.0.60

The problem exists in Emacs 27, so this isn't fixing a regression.  On
the other hand, it only affects forwarding with MH-E.

thanks,
mike
