Changes from 0.55 => 0.56
-------------------------
- [Security] Fixed bug when mutt is compiled with +USE_SETGID where a normal
  user can read anyone's mailbox when the mailbox is specified on the
  command line (this hole does not exist when using the change-folder
  function once inside Mutt, tho).

- [New] new function search-body (default: "S") to search for a regexp in
  message bodies.  Note: This currently does NOT do any MIME decoding

- really fixed the my_hdr infinite loop this time. . .

- generic menu driver now honors $arrow_cursor

- fixed bug where mutt would exit saying "externally modified mailbox" if
  you just touched the mailbox (i.e., no change in the size of the mailbox)

- lines in the body of a message was displayed as 0 if the last message in
  the mailbox has a Content-Length field but no Lines field

- modified rfc822 address parsing code to not strip quotes from comment
  fields

- doing a tag-group-reply (";g") now includes addresses from all messages in
  the default To and Cc fields for the new message (duplicates are
  automatically removed)

- better handling of invalid addresses in muttrc statements (alias,
  alternates)

- fixed problem with displaying 8-bit chars in ci_enter_string()

- Hacked q_encode_string() to skip re: and fwd: at the beginning of a string

- fixed display problem when using the folder-menu from the save-message
  prompt

- "mutt -v" now shows (+/-)HAVE_GNU_REGEX

From: Liviu Daia <daia@stoilow.imar.ro>
- fixed many references in the html version of the manual (thanks!)
- fixed the handling of $save_name
- ci_pipe_message() needed a wait() to allow for interactive programs to
  finish
- fixed segfault when re-postponing a reply to a message
- fixed display problem when flagging the only message in a mailbox
- fixed bug where MIME attachments would not be restored when recalling a
  message via the "-p" command line option.
- ispell should be called with the "-x" command line option
- change-folder now remembers the last directory visited when using the "?"
  menu

From: Christophe Kalt <kalt@stealth.net>
- mbox-hook's were not expanded before matching
- added error messages to go along with the beeps in the internal-pager to
  make it a little more user friendly

From: Brandon Long <blong@uiuc.edu>
- history pointer was not returned to the end of the list which caused it to
  be difficult to access the last item easily after moving around in the
  list.
