Revision 423394

Update to 1.7.0. The sidebar patch is now an official part of mutt,
and is now controlled by a SIDEBAR option. The trash patch is now
a non-optional part of mutt so its knob has disappeared completely.

Also, pass maintainership to submitter. Udo has looked after this
port for a long time; many thanks to him for all his work!

Changes for 1.7.0:

  ! Improved alignment when using multi-column characters with
    soft-fill (%*X) and right-justified (%>X) format strings.
  + The COLUMNS environment variable will be set to the width of the
    pager when invoking display filters.  This can be used in
    copiousoutput mailcap entries to allow their output to match the
    pager width.
  + The sidebar patch has been merged.  Please watch for airborne
    bovine.  See the documentation for all the options, or simply
    enable it with 'set sidebar_visible'.
  + $mail_check_stats and $mail_check_stats_interval control whether,
    and how often, to scan for unread, flagged, and total message
    counts when checking for new mail in mailboxes.  These statistics
    can be displayed in the sidebar and browser.
  + $trash, when set, specifies the path of the folder where mails
    marked for deletion will be moved, instead of being irremediably
    purged.
  + The <purge-message> function can be used to delete an entry and
    bypass the trash folder.
  + $folder_format has new format strings %m and %n, to display
    total and unread message counts for mailboxes.  Note that
    $mail_check_stats should be enabled to use these.
  ! When browsing IMAP, %N will now display 'N', instead of the unread
    message count.  Please use %n to display unread messages.
