The correct description is that the contents are emphasized.  I agree
that the manual could be changed.

Most likely <em>.

There are now other options for math formatting in HTML, but they are
suitable for TeX/LaTeX math, not much for text describing math.  If I
understand well your need, I think that using CSS to change how @math is
formatted is probably the best with --css-include.  And probably
something like

em.math { font-family:inherit }

It is possible that in 6.8 there is no math class, but in the upcoming
release there is.
