Thanks, but it would still be good to know which code changes the
mouse pointer to hand.  In the above patch, the only part that could
perhaps cause that is the first hunk, in dispnew.c, but I don't see an
immediate connection, especially since the answer is probably
somewhere in X-specific code (xterm.c etc.).
