Yes. What always confuses me is that <sup> has _descender_, while
<sub> has _ascender_; very perverse notation :)

Yes, it looks pretty simple, and probably I would do that, but I also
want to be able to render <i>foo</i> as _foo_, <b>bar</b> as *bar*
etc, and all that not always, but in a specific printing mode.

I think that the reduction of ^{n} to ^n is not very essential, though
it may produce nicer rendition. For me it would be quite OK if the
algorithm could take notice the appearance in the superscript of a
single plain ASCII character (i.e. neither & or <).

It would be quite OK for me to see A^{n²} or A^{n^2}.

What about dropping the parentheses in (TM)? Then you would typically
get Foo^{TM} or Bar^{R}. I admit that Bar^{®} looks worse.
