This patch is needed to get log4r to play nicely with newer versions of
Ruby…

 buff += format_object(event.data) + "\n"
 buff

The basic problem is newer versions of ruby correctly ban the mixing of
%*3$s format with %s.

John’s law :-

All advances in computing have arisen through the creation of an
additional level of indirection, the trick is to work out which
indirection is actually useful.
