UUCP Bug (brl-bmd.115 followup)

[utzoo!decvax!ucbvax!ihnss!cbosg!harpo!floyd!cmcl2!salkind]

There are several other minor bugs in expect():

	1) there can be a reference past the end of the statically
		allocated array rdvec (reported by someone else already)
	2) the alarm isn't reset (disabled)

The fix is simple.  In expect(), change the lines

		if ((*rp = nextch & 0177) != '\0')
			rp++;
		*rp = '\0';
		if (rp >= rdvec + MR)
			return(FAIL);

to
		if ((*rp = nextch & 0177) != '\0')
			rp++;
		if (rp >= rdvec + MR) {
			alarm(0);
			return(FAIL);
		}
		*rp = '\0';
