This is a suggestion to enhance the behavior of colorization of
unvisited/visited links as an aide for visually impaired readers.
Currently unvisited links appear in boldface red on a white background and
visited links appear as red (not boldface) on the same white background.
Suggest revising color scheme to use an alternate color as well as bold/not-bold
scheme. I spend a lot of time staring at links trying to decipher if I've
already been there. BVoldface alone is hard to detect when there is nothing to
compare it to.
