* simplify main loop (don't need `top' variable any more)
* use a struct sockaddr_in6.sin6_addr for the result from inet_pton(),
rather than u_char buf[16]
* add a few more comments
* confirm(): move from util.c to cmds.c. display mnemonic string in its prompt.
add support for `q' (terminate current xfer), `?' (show help list)
* in various signal handlers, output a linefeed only if fromatty.
* if fgets(stdin) returned NULL (i.e, EOF), clearerr(stdin) because you don't
want future fgets to fail. this is not done for the fgets() in the main
command loop, since ftp will quit at that point.
* unless ftp is invoked with -a, don't retain the anonftp setting between
hosts (`ftp somehost:' sets anonftp, but you don't want that to `stick'
if you close that connection and open a new one).
stage. if this occurs, just call lostpeer() to close the connection. whilst this
might be considered brutal, it's also extremely handy if you're impatient or there's
lossage at the remote end.
don't save the signal mask on some foreign systems.
* ensure signal handlers don't use stdio and do reset errno if they
don't exit with siglongjmp()
* use a common SIGINT handler for {send,recv}request()
(work around editline's override)
* minor cleanup of signal handler (along the lines of similar work in
recvrequest()). the handlers should now be reset everytime the cleanup
handler was callled.
prints out info if bytes > 0). only set the handler if SIGINFO is defined
* hijack SIGQUIT to be the same as SIGINFO (foreign ports have this, and it's
annoying to have SIGQUIT dump core on netbsd when it prints info on other
systems)
* in {recv,send}request(), factor a lot of duplicated code out into a
`cleanup' section at the end
* rework shell() a bit
* implement xsignal_restart(), which only sets the SA_RESTART flag if
specifically requested
* xsignal() is now a wrapper to xsignal_restart(). INFO, USR1, USR2 and WINCH
are restartable, ALRM, INT, PIPE and QUIT are not.
* improve getreply()'s timeout code to take advantage of the above.
other changes:
* improve wording of how globbing works for `classic' URLs (host:path).
suggested by John Refling <johnr@imageworks.com> in relation to PRs
[bin/8519] and [bin/8520]
* always compile in the `edit' command even if NO_EDITCOMPLETE defined.
it's just a no-op in the latter case, which is more consistent to
the users.
* always compile in about: support (i.e, remove NO_ABOUT).
i'm entitled to some vanity in this program...
* clean up some whitespace
the disabled state can be overridden by toggling epsv4.
(I got sick of the errors about EPSV not being supported on almost
every server I connect to. This way we retain support for epsv4, but
it's not so whiny after the first failure...)
to "extern" if it's not set. define GLOBAL to (empty) in main.c.
this effectively moves all the globals into main.c whilst retaining
namespace access to them in other source files.
(global vars in header files confuse foreign linkers)
should be in host order. found/fixed by Matthias Pfaller <leo@dachau.marco.de>
* parse_url(): improve checking of portnum, and add an extra argument to pass
back the parsed portnum to the caller (reduces a bit of code duplication)
* Move the KAME/WIDE copyrights after the BSD/TNFi ones. Since there was
significantly less code added under the former, it's only fair on the latter.
ETA might be over and will appear to drop rapidly, rather than being under
and appear not to change. the original code makes sense when you're testing
by suspending & resuming the client. however, the unfudged number is probably
better in reality, especially for slow spurty networks.

* implement docase() (a la dotrans() et al) and use appropriately, rototilling
some duplicated code
* globulize(): modify to return a pointer to the strdup()ed result in all cases,
and hack the code that calls it to take this into account
* replace strcpy() and strncpy() with strlcpy()
* put(), getit(): use some aptly named local vars instead of argv[...]

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
