Lennart's screenshot doesn't look good to me - it's underline merges
with the character bases (and doesn't break for the p descender like it
should if the underline is crossing it, but that's a more subtle issue).

However, it's probably font-dependent and font-size dependent.   I
imagine emacs could be using some metrics from the font to decide where
to position the underline...  And there's also a quantisation issue - at
small font pixel sizes, the "natural" position for an underline could
have to be distorted to match the pixel grid for a sharp, detached
underline.

Lennart, you might just try a different font and/or bigger font size,
see if the underline detaches from the bases...

Attached is what underline looks like on an out-of-box cvs build on my
system (which is apparently defaulting to bitstream vera sans.  In fact,
I can't seem to stop it using bitstream vera sans at the moment, but
that's another issue, see bug #35).

As you can see, it's not quite perfect (due to aforementioned descender
issues), but much nicer than Lennart's screenshot.
