[tex4ht] several bugs and a query

[Michal Hoftich]

Dear Alex,

I've been busy in the last week, so I was not able to take a look at
these issues yet. I hope that things will settle down soon, I will
start to process the issue queue then. No need to worry about the
number of issues.

Best regards,
Michal

> Just a follow-up about the bug reports/feature requests I sent out a week ago. I realize I asked for a lot all at once, so I thought I would single out a couple that are highest priority:
>
> 1. Superscript (and subscripts) not working in footnotes (https://tex.stackexchange.com/questions/474005/superscript-not-working-in-footnotes-in-tex4ht-output). This is the main one because it can't be fixed by find/replace. I use superscript to refer to the "recto" and "verso" of folios in medieval manuscripts (e.g., `folio 2\textsuperscript{r}` for the recto side of folio 2), and I use subscript for line numbers when referring to manuscripts or critical editions (e.g., `22\textsubscript{1-24}` for lines 1-24 of page 22). Especially in the latter case, information is actually lost in the conversion, since "221-24" means something quite different from "22, lines 1-24".

Less important because it's about formatting rather than information, but still problematic because it can't be fixed with find/replace, is the problem of spuriously italicized (or boldface) footnote hooks (https://tex.stackexchange.com/questions/474003/spuriously-italicized-footnote-hooks-in-tex4ht-output).
>
> The rest are less important. The section break issue can be fixed with find/replace in MS Word (find ^b = Section break, replace it with nothing). The section numbering issue is not an issue at all (I was confused). As for formatting footnotes, that is certainly not urgent!
