That's not a bug. When TortoiseMerge is started to 'compare with working
copy', then the unified diff is applied to the working copy, i.e. the
*patch* part of TortoiseMerge is used.
There's a difference between 'unified diff viewer' and 'patch tool'. But
since there are no UI patch tools out there except TortoiseMerge,
there's no setting for it in the settings dialog.
