Should this option be applied to the non-rectangular empty region
as well?  I.e. as soon as you type 'C-SPC' should it indicate
with the same narrow line that the selection is activated?
Or maybe such indication is not necessary if an empty region
is ignored anyway when use-empty-active-region is nil?
