Comment 3 for bug 489915

The current method of diff-ing multiple files with an external tool is also really clunky. It would be really nice if you could have two ways of working:

* If you're using a diff tool that supports tabs (e.g. diffuse), click "Using -> Diffuse" and it will open the complete diff with each file pair in a separate tab (diffuse old/%1 new/%1 -t old/%2 new/%2 -t old/%3 new/%3 etc etc etc)

* If you're using a diff tool that doesn't support multiple tabs (e.g. diffmerge), allow the user to select which file is opened. If you have scanned the brief view in qdiff and want to open a particular file in a full viewer with line numbers etc, you currently have to keep quitting the external diff app until you get to the right file, then have to quit it repeatedly afterwards to be able to use qbzr/bzr-explorer again
