I see.  This did not occur to me, as the LaTeX export seemed to work
(well, it produced an Undefined control sequence error that I did not
spot).

But it put me on the right (?) track: I now found that both \zwnj and
\shy seem to produce what I want without any need for customization.  I
do not know which one is the bigger hack...

Thanks for the clarification.  I like the meaningful name (although I'd
go for #+MACRO: sup \zwnj^{$1}).  That even makes up for the syntax
of macros and I'll use that.

Thanks!
