need info: %r in printf

[Guido van Rossum]

Since %r is - as far as I know - not standard, and the stated most common
use (in general error message printers) is as easily programmed as follows:

/* VARARGS 1 */	bug(fmt, a1, a2, ..., a10) char *fmt; {
	fprintf(stderr, "Error: ");
	fprintf(stderr, fmt, a1, a2, ..., a10);
	abort();
}

it seems better if DECUS had never introduced it in the first place.
The same is true for the "well-known hack" to pass a variable number
of arguments!!!--
