0.0.2

Changed

Some preliminary work towards robust cross platform support:

• Switched to using status -z instead of status --porcelain for obtaining
  work tree status. This adds a bit if parsing complexity, but should be the
  absolute most robust long term way to read things, and should enhance cross
  platform support in the future.
• Use TAB as IFS character for file-list instead of |. This should still be
  understandable by most shells but significantly less likely to appear in a
  filename.
