fix bug in french translation and another issue

Hi,

I send the french translation a few years ago, and it was incorporated in the
cvs. There was an error but I wasn't able to access cvs, and the mail
I sent to the maintainer were unanswered.

I have just found that the development continued here, thus I post 
the patch against 1.66 which corrects this little bug.

There is another issue:

para@^{i}tre, appears in the html output as para@^{i}tre (in the html
source: para@^{i}tre, should be paraître).

para@^{@dotless{i}}tre leads to the same para@^{i}tre in the html output.

para@^itre gives the right result with texi2html (in html: paraître).

The postscript output is right in the second case (para@^{@dotless{i}}tre), 
in the first and third case there is a i with a dot and a ^ above the dot.

The info output is the same in every cases.

In TeX, the right way of doing what I want to is to do \^\i, but it isn't the
same in texinfo, i tried similar things, but it doesn't work.

It seems to me that texi2html should handle the para@^{i}tre case, and then I
think the para@^{@dotless{i}}tre case would be the way to go to a a correct
document in html and dvi/ps.

Do you agree with this ? If yes I will try to do a patch.
