Ah, OK - I was just dense: I misread it completely.

OK: agreed - we just fix existing org files on a case-by-case basis.

So manually inserting "14." at the beginning of the line is user error,
auto-fill is taken care of by your patch. However, there is still the
problem that an empty item in a numbered list will trigger the error
that I posted, so org-html-export-list-line will need to be taught how
to deal with an empty list item - correct?
