NetBSD/usr.bin/mail/v7.local.c
christos f309875081 From Anon Ymous:
1) Statification of modules.

2) Implement the 'detach' and 'Detach' commands for extracting mime
   parts from messages.

3) Teach mail to output "In-Reply-To" and "References" header fields
   when replying so others can thread us.

4) Implement threading, sorting, and tagging, supported by the
   following commands: 'flatten', 'reverse', 'sort', 'thread',
   'unthread', 'down', 'tset', 'up', 'expose', 'hide', 'tag',
   'untag', 'invtags', 'tagbelow', 'hidetags', 'showtags'.
   See the manpage for details (when available - soon).

5) Implement a 'deldups' command to delete duplicate messages based on
   their "Message-Id" field, e.g., in replies to a mailing list that
   are also CCed to a subscriber.  (This can also be accomplished with
   the threading and tagging commands.)

6) Implement 'ifdef' and 'ifndef' commands, and make the conditionals
   nestable (i.e., implement a conditional stack).  The if/else/endif
   commands existed before, but they were primitive and undocumented.
   The 'if' command currently recognizes the "receiving", "sending",
   and "headersonly" mode keywords.

7) Teach the message selecting routine to understand regular
   expressions if "regex-search" is defined.  Otherwise only case
   insensitive substring matches are done (as in the past).

8) Teach the message selection routine to understand boolean
   expressions.  Improved "colon-modifier" support.  See the manpage
   for details (when available - soon).

9) Extend paging to all commands (where relevant).

10) Add shell like piping and redirection of (standard) output (if
   "enable-piping" is defined).  Extend completion to these contexts.

11) The manpage should follow soon!!!!
