LOADF-LOCATE
* LOADF-LOCATE ( "name" -- )

look for the filename created by LOADF that had been
defining the given name. LOADF has created a marker
that is above the INCLUDED file and that
marker has a body-value just below the
INCLUDED file. Hence the symbol was defined during
LOADF execution of that file.
