REVISION SUMMARY
  Sometimes other code, such as commit when using `commands.commit.post-status`,
  calls `commands.status()` without going through the normal dispatch mechanism
  that would typically fill in the args to be something besides None. As a
  "defense in depth" mechanism for a bug where Mercurial would crash if both
  `commands.commit.post-status` and `experimental.directaccess` were enabled,
  let's sanitize these values to be identical to the values they would have when
  the user invoked this method from the commandline.
