Does anyone even use Info these days?

Recent versions of texinfo seem to be able to turn @math into MathJax
when generating HTML.  (That said, recent versions of texinfo almost
don't include the one on the machine that currently builds the rotds.)

We could maybe try using conditionals, e.g. @iftex ... @end iftex, to at
least format maths nicely for those output targets where it is possible.
