commit 22d12cda4aed8d25fb79588a7261ca489db5ecd7
Author: Thomas Jarosch <thomas.jarosch@xxxxxxxxxxxxx>
Date: Mon Mar 16 20:05:22 2009 +0100
Improve indentation and whitespace cleanup
Reformatted using this astyle options:
/usr/bin/astyle --indent=spaces=4 --indent-switches --brackets=break \
--convert-tabs --one-line=keep-statements
--one-line=keep-blocks
Should have done this for a long time...
