Subject: [PATCH] org-occur requires a non-empty regexp for performance
Date: Sat, 01 Aug 2009 20:51:37 -0400 [thread overview]
Message-ID: <87skgb82cm.fsf@gimli.intra.norang.ca> (raw)
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
