ah.  how does one enter a zero-width space in emacs/org-mode?  also, i'm
curious about how it looks on the screen.  (for me, i'd want it to look,
on the screen, *very* obvious that *something* is there.)

i also apologize that the patch i sent before is incomplete -- i forgot
to modify a bit of "src_" processing; a new attempt is below.  (not sure
if that format is suitable.)

cheers, Greg
