- 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) 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!!!!
