I changed my mind on this after discovering that these variables do
not work as buffer local variables. Whatever the current buffer has it
set to causes all other visible buffers to draw in that way, which
causes underlines to jump around if they're set differently in
different buffers.

Please see attached patch. I don't have a windows or linux machine to
test on, so if someone could do that it would be appreciated. There
are some subtle differences in the original code which I tried to
respect.

I'm open to any advice on the naming/doc strings or implementation. Thanks!

Aaron
