If a blank regexp is provided to org-occur the function
goes away for a l-o-n-g time. We'll just bail out
instead up front to prevent an infinite loop.

I never actually let this run long enough to find out if
it is an infinite loop -- or if it just takes forever
to return results. I'm not that patient.
