I don't think so, because you want next to test for whitespace
where it _doesn't_ end in \r, i.e. this condition is here
because of the 'else' clause.  IIRC.

What I'm suggesting is this,

	if (/\s\r$/) {
		bad_line("trailing whitespace", $_);
	} else {
		if (/\s$/) {
			bad_line("trailing whitespace", $_);
		}
	}

Why only test for \r when all you want to know is whether there is
whitespace before \r ?  If there isn't whitespace and \r at the end
of a line, then only test for whitespace at the end of a line.

Unfortunately \r matches \s (is whitespace), so if line ends with CR LF
("\r\n") it wouldn't match first regexp, so it would go to 'else' 
clause, where it would match /\s$/ and it shouldn't.
