Right.  That seems to be satisfactory.  Thanks.
I had the impression from the doc's that the mozilla option would

Brilliant.  Thanks a lot.

Putting this inside an \AtBeginDocument{...} macro, I can put it
inside my custom style files (.4ht) and keep everything in one
place.  Apparently, one should also unset the white-space: pre property
on the code element, lest there be extra blank lines in the html rendering.
