HTML help is not right for math formula:
For example:
I got the following formula in help page of ca.jo in urca package:

<p align="center"><i><B>X</B>_t = <B>Pi</B>_1 <B>X</B>_{t-1} + ... + <B>Pi</B>_k
<B>X</B>_{t-k} + <B>&mu;</B> + <B>Phi D</B>_t + <B>varepsilon</B>_t
, quad (t = 1, ..., T),</i></p>

This presentation is just not good, however, in most browser,
with tag <math></math>, the formula in the tag works well.
such as in wikipedia. please check the same formula:

Can someone please fix this?
help(ca.jo,offline=TRUE), we can get the formula right.

The problem seems to occur at the building process. Latex output is
right, but the HTML output is not good for math formula.

I guess this issue is not so difficult.
