difftools, ‘bzr diff --using footool’ , and ‘diffuse’

[Stephen Ward]

Hi Ben,

The problem is that 'diffuse' doesn't know how to deal with directories, so 
the default behavior of the 'difftools' plugin messes it up (it defaults to a 
tree-oriented use-model).  This can be trivially fixed by adding one line to 
controller.py:

 register_diff_tool(TreeDiffTool('fldiff'))
+register_diff_tool(ListDiffTool('diffuse'))
 register_diff_tool(ListDiffTool('gvim', diff_options='-f -d'))

Or, of course, you can use the builtin implementation of 'diff --using', which 
works just fine for any of the list-oriented diff tools.

Regards,

Steve
