separated HTML/TeX/texinfo code trouble

[Patrick Guio]

Dear all,
The following piece of code is doing what I expect for the TeX version of
the documentation, i.e. a nice looking table. The texinfo version is also
behaving as expect, i.e. the @multitable @end multitable environnement.
But when it comes to the HTML version, I get the following problem, the
table is present twice; once with the @html @end html insertion and once
with from the @ifinfo @end ifinfo which is not what is expeced, is it?
