Don't log out player when update aborts a command under Windows

Browse source 
pthread.c's empth_select() returned 1 instead of 0 when empth_wakeup()
interrupted select().  This made io_input() attempt to read input,
which failed with WSAEWOULDBLOCK.  The failure then got propagated all
the way up, and the player got logged out.  Fix by returning 0 in that
case.
