* listing.c (struct file_info_struct): Rename end_pending field to

	at_end.
	(file_info): Initialize at_end, not end_pending.
	(buffer_line): If at_end set, just return immediately.  Don't
	worry about end_pending cases.  Set at_end when EOF is read.
	(print_source): Check at_end, not end_pending.
	(listing_listing): Likewise.
PR 6636.
