When a submodule commit had already been staged and another commit had been checked out inside the submodule, the diff always displayed the submodule commit log messages between the last supermodule commit and the working tree, totally ignoring the commit in the index.

This fixes a regression introduced by this recent patch of mine: "git-gui: display summary when showing diff of a submodule"

Sorry for the inconvenience.
