Subr version of INCLUDE

[JONL at MIT-MC (Jon L White)]

According to the generalized syntax rules that generated 
the other newio function names, this should be called
INCLUDEF  (after LENGTHF, DELETEF, PROBEF, ...)
Three different rules in maclisp syntax now permit putting a * in
the front of a name, and the one which would get you a subr version
of an fsubr is a very weak case, involving none of the newio subrs:
1) LSUBRs with restricted number of args; primarily for compiler output
   (e.g., *PRINT, *LESS, *QUO)
2) Name conflicts for features in semantic transition (e.g., *FUNCTION,
   *CATCH, *THROW, *REARRAY)
3) Subr version of some FSUBR - only *ARRAY and *BREAK.
