Oh, this must be a bug in the old exporter which I grew to depend upon.
FWIW I always set ^:nil to t, so that I can use underscores w/o
exporting subscript words.  Previously even with ^:nil, superscripts
using curly braces would be exported as superscripts.  I guess I'll have
to find a new mode of operation with the new exporter.
