test-obsolete: move a divergence related test from the main test Adding a new test file for test cases of evolution from an obsolete working directory parent. So this patch moves one divergence related case from test-obsolete.t to newly added test-evolve-obsolete.t and add few new cases as well. The new cases are probably there in other files, but not at the same place and I think having these cases in a single file make more sense. We can remove those duplicated tests from others file, let's see. In new test file there is one TODO (split case) which is yet to be written. I plan to add that after this, if that's not a blocker.
