While the segfault was fixed, there was another problem this test demonstrated: namely, that git would overwrite a dirty file involved in a rename. Further, the test encoded a "successful merge" and overwriting of this file as correct behavior. Modify the test so that it would still catch the segfault, but to require the correct behavior. Mark it as test_expect_failure for now too, since this second bug is not yet fixed. t7607 had a test added in 30fd3a5425 (merge overwrites unstaged changes in renamed file, 2012-04-15) specific to looking for a merge overwriting a dirty file involved in a rename, but it too actually encoded what I would term incorrect behavior: it expected the merge to succeed. Fix that, and add a few more checks to make sure that the merge really does produce the expected results.
