Make file icon for a moved and changed file different from one that has only been moved

Currently, in the staged file tree view, the down-and-to-the-right swoosh arrow is used for any file that has been moved. This is great. However, the same icon is used even if the moved file has been changed. This makes it impossible to see which files have been changed without going through each one and checking for a diff in the diff panel. It's be great if an appropriate variation of the move icon was used to indicate "moved and changed."
