running tex4ht with dvi output

[Karl Berry]

Hi Wybo,

    When I run texi2dvi 1.156 on test.tex:

    \documentclass{article}
    \begin{document}
    test
    \end{document}

    It creates files test.html, test.lg and test.idv
    This is because it runs tex4ht for some reason, 

As far as I can see, this has been lurking ever since Akim first
committed the run_tex4ht function in 1.150
(http://cvs.savannah.gnu.org/viewvc/texinfo/util/texi2dvi?root=texinfo&view=diff&r1=1.149&r2=1.150)

The case statement matches both dvi and html output, when as far as I
can see, all we want to match is html.

If I'm missing something obscure, no doubt Akim will inform us ...
Meanwhile, I committed this change.

Thanks,
Karl
