D6707: revset: drop argument when it's None

[av6 (Anton Shestakov)]

Herald added a reviewer: hg-reviewers.

REVISION SUMMARY
  getstack's definition is `getstack(repo, rev=None)`, so providing None
  explicitly is unnecessary. Moreover, when x is not None, it's definitely not a
  revision but a part of a parsed tree of revset arguments.

REPOSITORY
