PATCH: fg and bg tests

[Peter Stephenson <p.stephenson@xxxxxxxxxxx>]

Here's a way of testing fg and bg.  See if you can spot any problems
before the tests become too hairy to debug.

The time waiting for the ^z is already there in previous tests ---
nobody's apparently noticed any problems there.  Maybe we can avoid
them all with carefully chosen output, but I don't think it's trivial.
