tests: Skip tests if they will fail because of outer repo For different reasons these tests will fail if run in a tmpdir which is in a hg repo. The following three tests assumes no .hg in path dirs - I don't know how to work around that: * test-dispatch explicitly tests for no repo and expects "abort: There is no Mercurial repository here (.hg not found)!" * test-extension expects parentui to be None when not cd'ed to a repo dir * test-globalopts tests that implicit -R works correctly - that could perhaps be done from another repo instead of assuming no repo The following two might be worth investigating further: * test-convert-svn-sink fails for unknown reasons, starting with "abort: unresolved merge conflicts (see hg resolve)" * test-glog gets strange failures when testing "from outer space"
