Re: real subscripts and superscripts?

[Karl Berry]

Hi Pat,

    I add that I'd rather that we use specialized TeX renderers
    rather than handle it ourselves.

I agree.  A couple days ago, I took a few minutes to try to see if there
were any decent TeX math parsers in Perl that we could reuse.
Unfortunately, it did not seem so.  Everything I could find seemed to
have a different purpose or did not really work.  I don't know.

Speaking as one of the purported maintainers of tex4ht, I can say that I
don't think making it a dependency of Texinfo is a good idea.

Anyway, we're not going to solve the whole math problem right now.

As far as ^_ vs. @sup/@sub goes, should I infer from your reply
that you do not want to implement ^_ in texi2any?

Fine, if so.  In that case, @sup/@sub inside @math would clearly just
stay in math.  The remaining question would be about @sup/@sub outside
of math -- go into math by default, or stay in text?  I would be
inclined toward the latter (which is also what texi2any does now).

Thanks,
K
