[PATCH] diffcore-order: Default the order file to .git/info/order.

From: Geoffrey Thomas <geofft@mit.edu>
Date: Sep 12, 2009, 23:49 UTC
Message-ID: <1252799388-16295-1-git-send-email-geofft@mit.edu>

Since order files tend to be useful for all operations in the project/repository, add a default location for the order file, so that you don't have to specify -O<orderfile> on every diff or similar operation.
