Bug in xboard ICS play

[Simon Waters]

The intended release version of GNU Chess doesn't handle the
"result" command from xboard correctly on ICS.

Here "result {1-0|0-1|1/2-1/2|*} { ... arbitary comment .... }"

where first pair of braces denote "one off", and second pair
appear in message.

I think it might be a change in players.c, to memset, but I'm
not 100% sure.

Time to sleep here, but if anyone fancies hunting it whilst I'm
asleep, I think this needs fixing before release :-(
