GRUB_HIDDEN_TIMEOUT may cause double timeout count

Currently in grub 1.98 if a user enables the GRUB_HIDDEN_TIMEOUT entry
in  /etc/default/grub. The following code will be executed from

if sleep$verbose --interruptible ${GRUB_HIDDEN_TIMEOUT} ; then
 set timeout=${GRUB_TIMEOUT}

That code performs the hidden timeout.  Either when it expires, or is
aborted with a key, it will start the regular timeout also.  This
behavior can be reproduced.

Here is a patch that changes that ${GRUB_TIMEOUT} to 0.
