Subject: Doc: de-document unimplemented geometric operators.

In commit 791090bd7, I made an effort to fill in documentation
for all geometric operators listed in pg_operator.  However,
it now appears that at least some of the omissions may have been
intentional, because some of those operator entries point at
unimplemented stub functions.  Remove those from the docs again.

(In HEAD, poly_distance stays, because c5c192d7b just added an
implementation for it.)

Per complaint from Anton Voloshin.
