[PATCH] Fix Subject when forwarding message with 2-line From |

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

* lisp/mh-e/mh-comp.el (mh-forwarded-letter-subject): Collapse
two-line From headers into a single line (SF#266). Based on a
suggestion from Lester Buck (many thanks!).
