With 6.8, I can see, for instance in the generated MPFR manual:

  <em class='math'><var>d</var> times 2 raised to <var>exp</var></em>

However, the CSS solution won't work with lynx. There is no italic in
this case, but the text is still emphasized (with a different color),
which is rather disturbing.
