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.

This patch is available at git://git.norang.ca/org-mode.git for-carsten
