[Feature Request] Support visualisation of diff files.
There are often cases where I am expected to review changes based solely on the patch or diff file, and it's likewise the case that I do not need to use a diff application to generate the diff file.
It would be awesome if I could open a diff file and for meld to show the file in a visual manner. It may mean using ellipses (or a visual metaphor equivalent) for 'difference only' files - but it would be so useful.
