 1.13  09-Jul-2025  rillig mail: fix lint warnings

No binary change, except for one line number in an assertion.
 1.12  24-Oct-2019  kamil branches: 1.12.10;
Switch the iconv(3) prototype to the POSIX conformant variation

Remove const from the 2nd argument.

const char ** and char ** are incompatible types and it was a cost to keep
the technically incompatible form for a more purist variation. NetBSD was
almost the last alive OS to still keep the const argument (known leftovers:
Minix and Illumos).

Keep the const form for the internal purposes inside citrus and rump.

Address the build breakage fallout in the same change.

There are no ABI changes.

Change accepted by core@.
 1.11  14-Feb-2013  christos branches: 1.11.30;
PR/47657: Steffen "Daode" Nurpmeso: quoted printable CTE exceeds RFC limit.
- Encapsulated all the content-transfer-encoding stuff in mime_codecs.c
- Replaced calls of strtol(3) with a handcrafted version that allows simple
error checking by testing the return value. This allows to easily add
special code to handle illegal QP sequences.
 1.10  24-Nov-2012  christos PR/47237: Steffen Nurpmeso: Detect more than 2 pad characters and mark as bad.
 1.9  10-Apr-2009  christos branches: 1.9.6; 1.9.12;
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.
 1.8  18-Jan-2009  lukem branches: 1.8.2;
fix -Wsign-compare issues
 1.7  28-Apr-2008  martin Remove clause 3 and 4 from TNF licenses
 1.6  23-Oct-2007  christos branches: 1.6.6;
From Anon Ymous:
- 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.
 1.5  28-Nov-2006  christos branches: 1.5.8;
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!!!!
 1.4  24-Oct-2006  christos more meaningful variable name.
 1.3  23-Oct-2006  christos deal with machines where char is unsigned and with chars > 127
 1.2  22-Oct-2006  mrg avoid assigning a void * to an int just to see if it is non-zero or not.
use %zu to print a size_t.

- mime and character set handling
- command line editor and completion
- many code improvements
