In the current sources it's `ibuffer-maybe-show-predicates' and C-u g
to display buffers that match.

I'm not sure the current behaviour is a total misfeature because I
like to break out of displaying buffers matching
`ibuffer-maybe-show-predicates' without killing the Ibuffer buffer and
reinvoking `ibuffer'.  However, I agree that it would also be nice for
Ibuffer to behave as you expect.

How about making C-u g toggle whether it and subsequent invocations of
g should display buffers matching `ibuffer-maybe-show-predicates' ?
WDYT?
