I'm not sure I follow: explanation for what? The ":height 0.1" part is supposed to explain that the intent is to display a thin horizontal line, except that TTY frames don't support variable-height lines, so you see a normal-height line there in inverse video. > Anyway, it looks somewhat scary for an unprepared user.

I'm sure that whoever coded this thought it to be a very coll feature, so all I can advise is to get used to it. > I doubt that even experienced users know about this feature. Well, I, for one, do. Not every surprising feature should be an immediate candidate for removal.
