Well, you could write a cheapo function that goes:

strlimcat (char *s1, char *s2, int n)
{
   strncat (s1, s2, (n - strlen(s1)));
}

which is exactly what strlimcat would have to do anyway..

Ooohhh. Does that mean that C is frozen for eternity? The "ultimate,
greatest-ever language on earth"?  I hardly think so.

I think this is an appropriate place for suggestions for extensions to the
language, too, in addition to questions about clarifications of items in
the current standard...
