Spencer Thomas replied to a previous message requesting a predicate
to distinguish a C function from one that's defined in Emacs Lisp.  GNU
Emacs already has a "c-function-p" predicate: subrp.  Given a function
object (such as what symbol-function would return), subrp will return
T if that object was defined in C, and nil if not.
