? I'm curious: How/who/when/why does a property 'read-face-name
ever get set?

The Emacs Lisp reference manual (2.8 for 21.2) has no index entry
for it:

  "No `read-face-name' in index"

There is a function for it in faces.el, but the function seems to be for
interactively reading a face name from the user, and I didn't see
anything in the code that would make a text property out of it.

Grepping in share/emacs/21.2/lisp/*.el doesn't seem to turn up anything
more enlightening either.
