Yes, using an old version of DejaGNU will merely imply the old semantics
(i.e. folding the "break" and "continue" exceptions into a mere "return")
enforced at the lower level by remote_expect; we should therefore not rely
on correct operation of the exceptions until we've decided we require at
least DejaGNU 1.5 (in a few years' time I suppose).
Obviously nothing prominent relies on the old semantics within our test
suite or the switch would have caused regressions. I could have missed an
obscure architecture-specific test case of course or some failure paths
that are not triggered for successful runs (for obvious reasons these are
more error prone as they are hopefully ;) less regularly tested than the
corresponding success paths). Either of which should be fixed in a
backward compatible manner by replacing "break" or "continue" with
"return" where appropriate.

Applied now, thanks for the review.
