OK - it took me a while to realise this is the same because the new code
is jumping out a nesting level...

>   * diff command: inline rundiff, cleanup, add a debug message and comments

...which you then explain in this patch :-)

>   * diff command: cleanup imports
>   * diff command: move helper functions to the end 
>   * diff command: pull check for correct %1/%2 usage into getDiffCmdAndArgs
