Fix some of the glaring errors in GIT_DIFF_REVERSE These changes fix the basic problem with GIT_DIFF_REVERSE being broken for text diffs. The reversed diff entries were getting added to the git_diff correctly, but some of the metadata was kept incorrectly in a way that prevented the text diffs from being generated correctly. Once I fixed that, it became clear that it was not possible to merge reversed diffs correctly. This has a first pass at fixing that problem. We probably need more tests to make sure that is really fixed thoroughly.
