 1.23  03-Feb-2019  mrg - add or adjust /* FALLTHROUGH */ where appropriate
- add __unreachable() after functions that can return but won't in
this case, and thus can't be marked __dead easily
 1.22  12-Apr-2009  lukem branches: 1.22.38; 1.22.46;
Fix numerous WARNS=4 issues (-Wcast-qual -Wsign-compare).
 1.21  29-Jun-2005  christos branches: 1.21.30;
Add NO_USAGE and NO_DEBUG so that we can fit in the floppies again.
 1.20  07-Aug-2003  agc branches: 1.20.6;
Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22365, verified by myself.
 1.19  01-Feb-2002  itojun line2 may overrun if line is too long (> 200). be more careful on strcpy.
XXX strlen(argv[x]) should be checked before copies.
 1.18  15-Dec-2000  lukem invoke cmdtab.c_handler()s with argv[0] == c_name instead of the
supplied name. that way the full (unambiguous) name is displayed in
error messages and usage strings.
 1.17  18-Jul-2000  lukem convert to new knf
 1.16  01-May-2000  lukem convert to ANSI KNF
 1.15  11-Nov-1999  lukem whitespace nits
 1.14  24-Oct-1999  lukem new features:
- add `usage'; displays the usage of a command.
implemented by calling the c_handler() with argc = 0, argv = "funcname".
- add `passive auto'; does the same as $FTPMODE=auto.
- add `set [option value]'; display all options, or set an option to a value.
- add `unset option'; unset an option.
- add getoptionvalue() to retrieve an option's value, and replace a few
global variables with calls to this.
- implement cleanuppeer(), which resets various bits of state back to
`disconnected'. call in disconnect() and lostpeer().
- support completing on `options'.
- improve recovery after a SIGINT may have closed the connection.
XXX: there's still a couple to fix

other stuff:
- various consistency fixes in the man page.
- ensure that the command usage strings in the code and man page match reality.
- mput/mget: check that the connection still exists before each xfer.
- minor cosmetic changes in confirm().
- set code correctly in sizecmd() and modtime()
- don't need \n in err() strings.
- change lostpeer to take an argument (rather than casting (sig_t)lostpeer
in signal handlers)
- knf and whitespace police.
 1.13  27-Sep-1999  lukem * idle(): rename to idlecmd(). certain linux distributions have an incompatible
prototype for idle() in <unistd.h> (which i thought was against namespace
and sensibility guidelines, but...)
* consistently use xsignal() instead of signal(). we get known behaviour
in all cases (SA_RESTART), which is good for some borken foreign systems.
* remove signal.h from most files; it's unnecessary now
* fetch_url(): use `long chunksize' instead of ssize_t; it's more portable, and
we're setting chunksize with strtol() anyway
* xsignal(): only use SA_RESTART if it exists. SunOS 4.x doesn't have it
but has the inverse (SA_INTERRUPT). the original function i was inspired
from had this support (lib/signal.c, W. Richard Stevens' `UNP 2nd ed Vol 1').
* remove <termios.h> from util.c; it should be unnecessary now
 1.12  04-Jun-1998  lukem branches: 1.12.4;
some fixes & enhancements from openbsd's ftp, with extra fixes by me:
* default to passive with active fallback. $FTPMODE modifies this behaviour.
-A forces active connection.
* support '-o outfile' for auto-fetched files. outfile can be a file,
`-' (for stdout), or '|command' (to output each file through command).
* support '-r waittime', which retries the connection after waittime seconds
if it fails.
* fix 'page file' when restart is non-zero.
* try all ip-addresses of a host in a http fetch (as the normal ftp fetch
does).

XXX: a ``broken pipe'' error sometimes occurs with -o '|command';
i haven't tracked this down yet.
 1.11  20-May-1998  christos - cast arg to is*() to unsigned char.
 1.10  20-Jul-1997  lukem branches: 1.10.2;
* use RCSID() && COPYRIGHT() macros
* cleanup for WARNS=1 (including some ugly '(void)&var' bits wrapped in
#ifdef __GNUC__ to shut up gcc warnings WRT setjmp/longjmp)
* use strtol() instead of atoi(), and more extensively check result of
conversion
* use u_int16_t instead of short or int for TCP port addresses
 1.9  13-Mar-1997  lukem Features:
* support remglobbing of auto_fetch arguments
* new flag - '-e'; disable editing
* "page file" == "get file |${PAGER-less}"

Bugfixes/cleanup:
* consistently use a trailing '.' on messages
* code cleanup, including buffer overrun fixes, use puts
and putchar in places, etc (inspired by OpenBSD mods)
* disable progress bar when local-file is a pipe or '-'
* skip \r in http headers
* fix remote ftpd slash bug more elegantly (so it works with ////)
* abort_remote(): check if cout==NULL before using it. should fix [bin/3273]
* fixed up cosmetic problems when complete_remote() generated errors from the
remote server (such as "no files found", "login with user and pass", ...)
done by adding extra argument to remglob(), which is a pointer to an error
buffer to put messages in rather than printing to stdout.
 1.8  19-Jan-1997  lukem New features:
* Command line editing via editline(3) library.
* Context sensitive command and file completion, including remote files.

Enhancements to auto-fetch feature:
* Support for http:// URLs using the http protocol, including proxy HTTP
support via $htty_proxy if it's defined.
* The connection is kept open between successive files on the same host.
(obviously, this does not count for http requests.)
* Return value of ftp is 0 on no error, or the offset in argv[] of the file
which failed (i.e., argv[x] failed, ftp returns x).
* If the path in an ftp URL or classic format line has a trailing '/',
cd to the path and enter interactive mode. Fixes [bin/3011], albiet
requiring the user to help ftp in determining the operation.

Other changes:
* '-P port' works for normal ftp, and is the default for all classic style
auto-fetch transfers and for ftp URLs that don't specify the port.
(previously it would just work for the first xfer.)
* Some code moved into separated files along logical divisions.
* Editing and completion can be compiled out with -DSMALLFTP.
 1.7  09-Jan-1997  tls RCS ID police
 1.6  28-Nov-1996  lukem More features, some of which were inspired by changes that
friedman@gnu.ai.mit.edu (Noah Friedman) made to his modified ftp:
- implement "lpwd" - local pwd
- implement "preserve" - toggle preserving of file modification
times on retrieved files
- allow for explicit "on" or "off" arg to toggle commands
- "exit" synonym for "quit", "msend" synonym for "mput"
- in confirmation mode, allow 'a' (yes to rest of current command),
and 'p' (turn off prompt mode, as if 'prompt off' was done,
effective immediately)
- "modtime" returns time formatted as localtime, not GMT

Bug fixes:
- check for extraneous args on commands
- cleanup const usage, line formatting
- create 0 length temporary file in remglob() to prevent symlink games
(from OpenBSD)
- check length of filename of ~/.netrc (from OpenBSD)
