#13 builtins could use a leading comment

I suggest a comment before the definition of
builtins in interp/functab.c, telling the
developer that the entries of builtins MUST
be in alphabetic order (because an alphabetic
binary sort is performed directly on this list).

Good idea. I'll add the comment soon.

Fixed in CVS.
