The purpose of the function update_index_from_diff() (which is the callback function we give do_diff_cache()) is to update those index entries which differ from the given commit. Since do_diff_cache() plays games with the in-memory index, this function discarded the cache and reread it. Then, back in the function read_from_tree() we wrote the index. Of course, this broke down when there were no changes and update_index_from_diff() was not called, and therefore the mangled index was not discarded. The solution is to move the index writing into the function update_index_from_diff(). Noticed by Björn Steinbrink.
