- Introduce date_to_tm() and hl_date_to_tm() to parse the date and
headline date a bit more efficiently.
- If 'tm_isdst' is determined, let strftime(3) handle the '%Z' and
'%z' formats. Otherwise, output "-0000" and "???", respectively, to
help preserve with alignment; strftime(3) will output an empty
string in these case.
- Change fail() to use the '-d' flag (which sets the 'debug' variable)
rather than the "debug" _environment_ variable. This is more
consistent with other warnings.
- Don't use gcc C extensions, e.g., "case LOW ... HIGH:".
- Define is_WSP() in def.h to be an inline function that for checks
whitespace (WSP = ' ' or '\t'), as defined in RFC 2822. Use it
consistently in place of isblank().
- For consistency, rename skip_blank() to skip_WSP().
- Add inline skip_space() to complement skip_blank() (now skip_WSP).
- Check all ctype(3) calls for argument range issues.
- Whitespace and comment cleanup/changes.
1) Add support for message selection based on the message body. The
pattern matching is done on the MIME decoded body as would be seen by
the print command.
2) Don't hook editline when doing headers only: that mode is never
interactive and it messes up piping if output is redirected to a
command that expects tty input, such as 'more'.
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!!!!
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).

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.
1) Use editline [optional]:
Most of this code was borrowed from src/usr.bin/ftp. It does the
appropriate editing, history, and completion for all mail commands
(from cmdtab[]) and also does editing on header strings ('~h' inside
the mail editor).
2) '-B' flag:
This will suppress the "To:" line passed to sendmail. In most
configurations it will lead to sendmail adding "To: undisclosed
recipients;". Currently, AFAIK mail requires at least one exposed
recipient address.
3) Comments in rcfile:
Currently, comments in .mailrc are only supported if the first
(non-white) character on a line is '#' followed by white space,
i.e., '#' is a 'nop' command. This (trivial) patch allows the more
normal/expected use of '#' as a comment character. It does not
respect quoting, so that might be an objection which I should fix.
4) Sendmail option editing:
This adds the sendmail option string to the strings editable by the
'~h' command within the mail editor. Currently, you can only set
this string from the command-line, which is particularly annoying
when replying to mail.
5) Reply from:
When replying to a message, grab the "To:" address from the message
and, if there is only one such address and it does not match a list of
allowed addresses (set in the "ReplyFrom" variable), pass it to
sendmail as the "From:" address for the reply (with the '-f' option).
I often make aliases for myself so that my primary address is not
given out; if the alias gets out, I know who to blame. Unfortunately,
a reply to such a message would normally use the primary address
without this patch. A warning is displayed when this is going to
happen so that it can be modified with '~h'.
6) CC and BCC lists:
Allow '-c' and '-b' to accept white-space or ',' delimited lists.
Currently, a white-space delimited list of addresses work, but a
list of aliases will not get expanded. For example, currently:
mail -c "foo bar" christos
will fail to send mail to 'foo' and 'bar' if these are mail aliases
(in ~/.mailrc); sendmail aliases (in /etc/aliases) do work.
7) pipe command:
This pipes the current message into a shell command. I use this for
quick decoding of uuencoded mail, but I can imagine it might be
useful for decrypting encrypted mail, too.
8) show command:
This command takes a list of variables and shows their values. It
is probably stupid as the 'set' command without any argument
displays all variable values. Of course, if there are a lot of
variables you have to sift through the list for the one(s) you want.
