  Changed paths:
    M .gitignore
    M src/zope/error/_compat.py
    M src/zope/error/error.py
    M src/zope/error/tests.py

  Log Message:
  -----------
  100% test coverage.

Builds on #5 because that's what enabled coverage in the first place.

- Added missing tests.
- Whitespace cleanup in errors.py and tests.py.
- Replace branches in _compat.py with imports from six for coverage
  reasons. This may eventually be completely replaced by #7.
- The zope.testing cleanup function resets properties of the
  globalErrorReportingUtility (necessary because we have test cases
  that change them).
