bug#7408: 23.2.1 dolist -- subr.el and cl-macs differ with nil-block return

Don't know about "should", but it can be one of the cases where you
might want to do that, yes.  Of course, you can also change your code to
use catch&throw instead (which is what's used by `return' under the
hood, AFAIK).
