With the foo.el below, running

    emacs -Q -batch -l foo.el

gets a segv.  Backtrace from a "-O0 -g" build below.

I don't expect window handling stuff to actually show anything in -batch
mode, but I hoped it wouldn't segfault.  (Emacs 23 doesn't, didn't.)

I see the backtrace says something "MOUSE_HL_INFO".  The build is with
gpm and with the gpm server when running, but I don't know if it ends up
being used in -batch.
