sms-pdu-decode family: fix VP-Relative header spacing When VP-Relative is small enough to be reckoned in 5 min or 30 min units, it was printed incorrectly, with a cosmetic defect of one extra space. Fix this bug.

char *
rindex(p, ch)
	register char *p, ch;
{
	register char *save;

	for (save = 0;; ++p) {
		if (*p == ch)
			save = p;
		if (!*p)
			return(save);
	}
	/* NOTREACHED */
}
