I think that extracting "<foo>" from "<foo> <bar>" wouldn't be better.
Beacuse, there would be a problem when regexp extracts existing
Message-ID from invalid header.  If "<foo>" is existing Message-ID,
wl-summary-jump-to-msg-by-message-id may pick the wrong message.

I think "\\`[ \t\n]*\\(<.+>\\)[ \t\n]*$\\'" is the most safe to avoid
the above problem.  But I doubt whether the above problem actually
occurs, because I couldn't imagine recent programs create such insane
Message-ID: header.  So, I feel the most loose "<.+>" whould be
adequate.
