import-checker: recognize relative imports from parents of current package So far fromlocal recognizes relative imports of the form: from . import D from .. import E It wasn't prepared for recognizing relative imports like: from ..F import G The bug was not found so far because all relative imports starting from the parent was in the list of allowsymbolicimports like: from ..i18n import from ..node import

tests: test-check-py3-compat.t output updated The test output was not updated as the lower section of the test updates with python3.5, so it might be the case that people have updated the modules but the test was left as it was. So this patch updates the test output.

revset: factor out public optimize() function from recursion New optimize() hides internal arguments and return values. This makes it easy to add more parameters and return values to _optimize().

revset: introduce temporary variables in optimize() where they look better

revset: construct arguments of only() against matched tree Since _isonly() knows the structure of 'revs' and 'bases', it should be slightly easier to understand than destructuring 'ta' and 'tb'.
