Again, this is not about `eval-region', which _does not redefine_ a face or var
that is already defined.  It's about the special behavior provided by
`eval-defun' which does redefine.

And I'm interested in a redefining command/key, not making the user activate the
region around a sub-sexp before asking for redefinition.  A command/key can find
the innermost defface etc. surrounding point without any need for the user to
first select it as the region.
