Subject: Re: [PATCH] Use save-excursion in org-map-dblocks
Date: Wed, 24 Mar 2010 12:16:20 +0100	[thread overview]

Hi Magnus,

this looks like an OK patch and I don't have any problems applying it.
However, I do not quite understand the need for it.  Can you please  
try to
explain a bit better?  Do you have two processes running over the same  
file
at the same time, or why is there a conflict?

Thanks for your time.

- Carsten
