/*
 *	fprformat
 *	common code for printf fprintf & sprintf
 *	This is the variant that uses stdio und directly calls putc.
 *	If putc() is a FILE * derived macro, then a printf() based on this
 * 	variant is faster than a format() based printf that needs to call a
 *	function for every character in the output.
 *
 *	allows recursive printf with "%r", used in:
 *	error, comerr, comerrno, errmsg, errmsgno and the like
