only be using if their compilers didn't support IPv6, but now it

Proxy command formatting now recognises `%proxyhost' and
`%proxyport' in addition to the other things it interpolates. This
is useful when using the Unix-only `Local' proxy type: it allows me
to, for example, set up a proxy command such as
ssh %proxyhost nc -q0 %host %port
and then enter the name of the proxy machine in `Proxy hostname',
which makes it marginally more convenient to quickly change to using
a different proxy to get at the same target.
I haven't documented this, because we currently don't document the
Local proxy type at all. Possibly we should, though.

I've decided that trying to do wildcards in PSFTP as a special case
of directory recursion was a strategic error: it obfuscates
sftp_{get,put}_file(), and also it makes it very hard to handle
subdirectory wildcards such as `foo/*'. Accordingly, here's a
completely different approach, in which sftp_{get,put}_file() are
still responsible for directory recursion, but wildcards are
expanded in sftp_general_{get,put}() before being passed thereto.
Subdirectory wildcards are now handled consistently across Unix,
Windows and the remote server.

SSH port forwarding is now configurable in mid-session. After doing
Change Settings, the port forwarding setup function is run again,
and tags all existing port forwardings as `do not keep'. Then it
iterates through the config in the normal way; when it encounters a
port forwarding which is already in the tree, it tags it `keep'
rather than setting it up from scratch. Finally, it goes through the
tree and removes any that haven't been labelled `keep'. Hence,
editing the list of forwardings in Change Settings has the effect of
cancelling any forwardings you remove, and adding any new ones.
The SSH panel now appears in the reconfig box, and is empty apart
from a message explaining that it has to be there for subpanels of
it to exist. Better wording for this message would be welcome.

Abstracted out the rather large port-forwarding setup code into a
routine which is common between SSH1 and SSH2. Since this routine is
not part of the coroutine system, this means it can't sit and wait
to get its various success/failure responses back. Hence, I've
introduced a system of queued packet handlers, each of which waits
for exactly one of a pair of messages (SSH1_SMSG_{SUCCESS,FAILURE}
or SSH2_MSG_REQUEST_{SUCCESS,FAILURE}), handles it when it arrives,
and automatically de-registers itself. Hence the port-forwarding
setup code can be called once, and then subsequent packets related
to it will automatically be handled as they arrive.
The real purpose of all this is that the infrastructure is now there
for me to arrange mid-session configurability of port forwarding.
However, a side benefit is that fewer round trips are involved in
session startup. I'd quite like to move more of the connection setup
(X forwarding, agent forwarding, pty allocation etc) to using the
new queued handler mechanism for this reason.

In my revamp of cursor handling I had assumed that you were supposed
to call _either_ do_text() _or_ do_cursor() on a given character
cell. In fact you're supposed to call do_text() no matter what, and
then call do_cursor() as well if it's got the cursor on it, since
do_cursor() _only_ draws the actual cursor, which often doesn't also
cause the text to get drawn.
I'm half tempted to change this in the interface, retire do_cursor()
as an external function and relegate it to an internal function in
each front end, and require that do_text() must fully process all
cursor attributes it is passed. However, I haven't done this yet.
