For 1.5.9: unlink_follow: follow symlinks when deleting mail from MH/Maildir

[Bardur Arantsson <spam@xxxxxxxxxxxxxxx>]

Please consider including this in 1.5.9:

This patch adds an option

      unlink_follow (bool, default=false)

If set, the option makes the MH/Maildir code follow symlinks
when unlinking a message.

This brings 'delete' in line with the default mutt behavior of following 
symlinks e.g. when saving/copying messages. However, it does change 
behavior in a 'destructive' way, so is off by default.

(Just a note about usefullness: This can be very handy in combination 
with e.g. mairix to allow deletion of messages through complex searches 
on multiple mailboxes -- or, most usefully *subsets* of complex 
searches, tagged using the mutt index of the search folder).

Cheers,
