- 1 -> EXIT_FAILURE
- preallocate child struct, since the signal handler can be called before
  wait_child, and we cannot allocate a child struct there. there is a signal
  race still here if the program exits and the signal handler is called before
  we allocate the struct.

From Anon Ymous:

- Remove all longjmp(3) calls from signal handlers.  Instead, we post
to an internal signal queue and check that periodically.  All signal
related code is now in sig.c, except for the SIGCHLD handler which
remains in popen.c as it is intimately tied to routines there.

- Handle SIGPIPE in type1() regardless of mime support, or else the
handler in execute() will prevent our error code from being returned
resulting in 'sawcom' not being set on the first command as it should.
This only affected the initial behavior of the "next" command without
mime support.

- Add the 'T' flag to many commands in cmdtab.c that should not look
like the first command.  E.g., start mail on a mailbox with multiple
messages, run "set foo", then "next", and watch the second message get
displayed rather than the first as is the case without the first "set"
command.

- Add file descriptor and file handle leak detection.  Enabled by
DEBUG_FILE_LEAK.  This will likely disappear in the future.

- Fix a long standing (since import in 1993) longjmp() bug in
edstop(): the jmpbuf was invalid when quit() is called at the end of
main.

- Fix a long standing bug (since import in 1993) in snarf() where it
didn't strip whitespace correctly if the line consisted only of
whitespace.

- Lint cleanup.

- New Feature: "Header" command.  This allows miscellaneous header
fields to be added to the header, e.g., "X-Organization:" or
"Reply-To:" fields.

- New Feature: "page-also" variable.  This allows the specification of
additional commands to page.  It is more flexible than "crt".

- Document the "pager-off" variable: if set, it disables paging
entirely.

From Anon Ymous:

- Add a "forward" command as requested by garbled@.
  From the manpage:

  forward
	  Takes a list of messages and prompts for an address (or
	  addresses) to forward each message to.  If no message list is
	  specified, the current message is used.  The mail editor is run
	  for each message allowing the user to enter a message that will
	  precede the forward message.  The message is sent as a multi-
	  part/mixed MIME encoded message.

- Add the ability to match messages that do (or do not) contain a
  header field.  E.g., the command "f ! /Subject:" will display the
  list of messages that are missing a "Subject" field.

- Teach savemail() to prefix fake headlines so the mbox doesn't get
  broken.

- Fixed a couple of "bugs" in the attachment editing routine.

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!!!!

More fixes from Anon Ymous:


1) Removed the -B flag (it was stupid on my part) and added a short
   description indicating how to accomplish the same thing under the
   "Sending Mail" section of man mail(1).

2) Added a -H flag to dump the headers and exit.  It takes optional
   flags to restrict to old, new, read, unread, and deleted messages
   (the later being kind of useless - it shares code with something
   that already had it).

3) Restored the 'Save' command which somehow got mistakenly removed in
   the last commit and add documentation for it!  (My apologies to
   its author.)

4) Added a 'mkread' command to mark messages as read (the inverse of
   'unread').  Should we also have a 'mknew' command?

5) Added a 'smopts' command to keep a database of addresses and
   sendmail options to be used when sending messages to those
   addresses.  See man mail(1) for a fuller description.

6) Added 'indentpreamble' and 'indentpostscript' variables whose
   values are inserted before and after a quoted message (~m or ~M
   escapes).
=20
7) Added string formatting abilities for the 'prompt', 'insertpreamble',
   'insertpostscript', and header display strings.  These strings
   support all the strftime() format parameters as well as many more
   specific to mail (see man mail(1)).

8) Fix the -a flag so that it only takes a single filename, unless
   "mime-attach-list" is defined.  This is more conventional and avoids
   unexpected whitespace issues.

Fix a bug introduced by Christos Zoulas in version 1.4.
He accidently moved the call to block the SIGCHLD to the wrong side of
the call to findchild().
Caused a coredump in one in every N thousand invocations of mail,
which I have been hunting for literally years.
Fixes PR 19696 from Mason Loring Bliss, too.

By the way, this is a prime example of why declarations of the form

struct foo *p = funcall();

are pure liquid evil.
