since there is a theoretical code path (via the crReturn loop after
asking an interactive question about a host key or crypto algorithm)
on which we can leave and return to do_ssh1_login between allocating

(In practice it shouldn't come up anyway with any of the current
implementations of the interactive question functions, not to mention
the unlikelihood of anyone non-specialist still using SSH-1, but
better safe than sorry.)

places we simply enforce by assertion that it will match the request
we sent out a moment ago: in fact it can also return NULL, so it makes
more sense to report a proper error message if it doesn't return the
expected value, and while we're at it, have that error message
whatever message was helpfully left in fxp_error() by
sftp_find_request when it failed.
To do this, I've written a centralised function in psftp.c called
sftp_wait_for_reply, which is handed a request that's just been sent
out and deals with the mechanics of waiting for its reply, returning
the reply when it arrives, and aborting with a sensible error if
anything else arrives instead. The numerous sites in psftp.c which
called sftp_find_request have all been rewritten to do this instead,
and as a side effect they now look more sensible. The only other uses
of sftp_find_request were in xfer_*load_gotpkt, which had to be
tweaked in its own way.
While I'm here, also fix memory management in sftp_find_request, which
was freeing its input packet on some but not all error return paths.

buffered in terminal.c indefinitely and only released when further
output turned up.
Arose because we suppress the call to term_out from term_data if a
drag-select is in progress, but when the drag-select ends we weren't
proactively calling term_out to release the buffered data. So if your
session generated some terminal output while you were in mid-select,
_and had stopped by the time you let go of the mouse button_, then the
output would just sit there until released by the next call to
term_data.

purpose for it.

and returns its error message as a string, instead of actually
printing it on standard error and exiting. Now we can preserve the
previous error behaviour when we get a nonexistent font name at
startup time, but no longer rudely terminate in mid-session if the

and into AM_CPPFLAGS. This is more conceptually sensible according to
my reading of the automake manual, and also has the specific desirable
effect that they move to the front of the command line, ahead of any
'system' type -I options that autoconf might have felt a need for.
A user reported that autoconf had added -I/usr/local/include to their
command line for the sake of a required header file, but their
/usr/local/include also turned out to include a thing called 'proxy.h'
(from libproxy, nothing to do with us) which shadowed our own proxy.h
and caused a build failure. This should fix that.

treat all socket closures as clean exits (because the protocol doesn't
provide for transferring a process exit code) could usefully at least
treat _socket errors_ as unclean exits. Patch the Telnet, Rlogin and
Raw backends to retain that information and return INT_MAX to the
frontend.
I wasn't sure whether it was better to solve this by modifying each
affected frontend, or each affected backend. I chose the latter, but
neither is really ideal; this is the sort of thing that makes me wish
we had a piece of fixed middleware in between, independent of both
platform and protocol.

attempting to call lineptr() with a y-coordinate off the bottom of the
screen and triggering the dreaded 'line==NULL' message box.
This crash can only occur if the bottommost line of the screen has the
LATTR_WRAPPED flag set, which as far as I can see you can only
contrive by constructing a LATTR_WRAPPED line further up the screen
and then moving it down using an insert-line escape sequence. That's
probably why this bug has been around forever without anyone coming
across it.

FormatMessage to get the OS's text for any error not in our own
translation table. Should eliminate the frustrating 'unknown error'.
(I haven't chosen to use FormatMessage unconditionally, because it
comes out with enormous messages along the lines of "No connection
could be made because the target machine actively refused it" in place
of "Connection refused" and I'm Unixy enough to prefer the latter.
Also, on older Windowses, Winsock error codes are in a separate API
segment and don't work with FormatMessage anyway.)

window. scroll() iterates that many times, so this prevents a tedious
wait if you give a very large parameter to ESC[L or ESC[M, for
example.
A side effect is that very large requests for upward scrolling in a
context that affects the scrollback will not actually wipe out the
whole scrollback: instead they push just the current lines of the
screen into the scrollback, and don't continue on to fill it up with
endless boring blank lines. I think this is likely to be more useful
in general, since it avoids wiping out lots of useful scrollback data
by mistake. I can imagine that people might have been using it
precisely _to_ wipe the scrollback in some situations, but if so then
they should use CSI 3 J instead.
