Hi,

>From glMultMatrixd(3):

    .P
    Where '$times$' denotes matrix multiplication,

This becomes the following HTML:

    <div class="Pp"></div>
    Where '
    <math class="eqn">
      <mrow><mo>&#215;</mo></mrow>
    </math>
    ' denotes matrix multiplication,

The newlines before and after the math element result in extra spaces
between the ' and the multiplication symbol.

Removing HTML_NLAROUND helps, but still results in a space after
the first ' that I haven't figured out:
