Oh, I see.  How do we describe it?  A keyword, perhaps?

Thank you for the explanation!  The case I had in mind was indeed the
one where the 'org-code' face now applies.

I am interested in making the results display as distinct elements.  The
reason is that it can sometimes be hard to tell what was there before
and what was generated by 'org-babel-execute-buffer' and related.

You are right to point out that adding font-lock rules for all the
possible #+results is not trivial.  Better leave it as-is.
