I'm sure that depends on your perspective about what's convenient.  The
advance warning feature may be convenient for you, but for me (and
apparently I'm not alone) it's a nuisance.  My patch simply allows
people to turn this feature off if they have the same experience as I
do.  Is there some reason it can't be accepted?
