until a 20ms select(2) timeout occurs, but if there is a continuous
stream of movement events, button events can be delayed indefinitely
because the select never has to wait long enough for a timeout.
The delay and mouse event reordering that result are very noticable
and sometimes quite frustrating when dragging windows etc. in X.
Add a simple mechanism that avoids this re-ordering. While a button
event is deferred, we discard up to 3 movement events to allow for
mouse jitter. If more movement events occur, then we immediately
timeout the deferred button event and let the movement proceed.
This change only affects the 3-button emulation case.
perform a key change, *and* our sequence numbers have wrapped,
ensure that the number of key changes is calculated correctly.
The previous code counted down from a negative number to zero,
re-encrypting the current key on each iteration - this took some
time and strangely enough got the answer wrong !!!
Fix a(nother) spelling mistake while I'm there.
Use -tag list in the FILES section to work around the bug
when .Pa font is not restored to its original value if one
of the -hang, -ohang, or -inset lists is used in the FILES
section. (The fix for the bug has just been submitted to
the GNU Groff maintainers.)
Also, fixed the Handbook reference in the SEE ALSO.

envoked -- don't use them (as return values from open()), then
(say) close(STDIN_FILENO) when daemonising.
This is done by grabbing 3 descriptors to /dev/null at startup and
releasing them after we've daemonised.

This is necessary because MPPE will combine the protocol id with the
payload received on the tun interface, encrypt it, then prepend its
own protocol id, effectively increasing the payload by two bytes.
