Thanks, I'll give that a shot, though that wasn't exactly what I was
asking about. I haven't seen the doc change that Eli Zaretskii has
pushed because I can't seem to get to savannah, but I was suggesting
that, given the name of the variable x-underline-at-descent-line, it'd
be nice if the natural height of the font was used rather than the
height + extra line spacing to determine where to place the underline.
Does that make sense? Basically, it'd place the underline at the same
place regardless of what line-spacing was set to (as if it were set to
nil).
