evolve: change in a test which demonstrate divergence resolution can break This patch just add "--any" flag to "hg evolve --content-divergent" in a test and changed output reflect that there is something which is not handled correctly. After looking into code I found that it is because of using a evolvestate value which is not updated i.e evolvestate['divergent'] Next patch will fix this problem.

tests: update the title of a test as it's not what it says I see that this test has conflict in relocation and in merging also. We do have a test for the case when only relocation leads to conflict.

obsexchange: avoid importing io/StringIO module with a different name Since we're not interested in the whole module, let's shorten the imports and aviod the lint warnings. Otherwise pep8-naming complains: - import io as StringIO: N812 lowercase imported as non lowercase - import StringIO as io: N813 camelcase imported as lowercase

evolve: remove unused StringIO import
