Show renamed files like git diff --cached?

[nyanpasu64]

Right now, when you stage files which are renamed from one location to another and have high similarity, Git Extensions, Sublime Merge, and git diff --cached tell you the file was renamed (and show a diff if present), but Git Cola shows a separate removal and creation.

I think it would be useful for Git Cola to show which files Git thinks are being renamed, and also display which lines were changed during the rename.

I assume this won't be applied to unstaged renames. git diff --cached doesn't show unstaged changes, and git diff doesn't identify file renames since the new filename isn't tracked. Sublime Merge doesn't identify the rename (instead showing a deleted file and an untracked file in separate categories), and I think Git Extensions doesn't identify the rename either (though it shows the deleted and untracked file in the same pane).
