* 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.
barring any more little things people want added ...]
New features:
* progressmeter is now asynchronous, so "stalled" transfers can be
detected. "- stalled -" is displayed instead of the ETA in this case.
When the xfer resumes, the time that the xfer was stalled for is
factored out of the ETA. It is debatable whether this is better than
not factoring it out, but I like it this way (I.e, if it stalls for 8
seconds and the ETA was 30 seconds, when it resumes the ETA will still
be 30 seconds).
* verbosity can be disabled on the command line (-V), so that in auto-fetch
mode the only lines displayed will be a description of the file, and
the progress bar (if possible)
* if the screen is resized (and detected via the SIGWINCH signal), the
progress bar will rescale automatically.
Bugs fixed:
* progress bar will not use the last character on the line, as this can
cause problems on some terminals
* screen dimensions (via ioctl(TIOCWINSZ)) should use stdout not stdin
* progressmeter() used some vars before initialising them
* ^D will quit now. [fixes bin/3162]
* use hstrerror() to generate error message for host name lookup failure.
* use getcwd instead of getwd (it should have been OK, but why tempt fate?)
* auto-fetch transfers will always return a positive exit value upon failure
or interruption, relative to the file's position in argv[].
* remote completion of / will work, without putting a leading "///".
This is actually a bug in ftpd(1), where "NLST /" prefixes all names
with "//", but fixing every ftpd(1) is not an option...
* 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.
