From: Johannes Schindelin <johannes.schindelin@xxxxxx> When running an external diff from, say, a diff tool, it is safe to assume that we want to write the files in question. On Windows, that means that there cannot be any other process holding an open handle to said files. So let's make sure that `git diff` itself is not holding any open handle to the files in question.
