Thanks for your replies.  I know that there are entrenched views on terminal
colours, but I doubt that there are many fans of yellow text on a white
background, which is how link urls come up with the default settings for
terminals and lynx in SL6.  Furthermore, I don't think that this arrangement
is intentional on the part of the lynx packagers because the link text had a
contrasting background in SL5 and I can't see any mention of it in a
changelog.  Everyone ought to be free to use the colour scheme of their
choice, but I see no point in having the distribution's default arrangement
be unreadable (and I'll bet the packagers don't either).

Connie, Pat, am I correct in guessing that the "el6" in the lynx package name
lynx-2.8.6-27.el6.x86_64 means that the packagers are at TUV and that the
best way to reach them is through their bugzilla?
