maybe you need to upgrade:

14:37:00 dieter at Gi ~ git --version
git version 1.7.4.1
14:37:44 dieter at Gi ~ man git-merge | grep -C 1 patience

           patience
               With this option, merge-recursive spends a little extra time to avoid mismerges that sometimes occur due to unimportant matching lines (e.g., braces from distinct functions). Use this when
               the branches to be merged have diverged wildly. See also git-diff(1) --patience.
