A bug then may occur at XEmacs-side if someone codes
the need for an exclusive `mark-active'/region-exists-p
with `region-active-p useroption'. XEmacs will not know
about that option, only reads `region-active-p' and
decision may be wrong.

XEmacs will always check for an extend if
`region-active-p' is written and maybe return `nil' in
cases, where it's not TRT.
