[l2h] Problem with \renewcommand

[Graham Gough]

This illustrates the necessity for following latex2html Rule No 1

  \emph{Always} put command definitions in the document preamble

and Rule No 2

   Avoid the defining the same command twice wherever possible

These rules are actually quite easy to follow and eliminate a lot of
latex2html problems. latex2html is not a full LaTeX engine and
definitions need to be handled with care
