  other modules when importing fails
  Notably, importing the anydbm module is fixed. (2248).
  Thanks pfhayes for the PR.

• junitxml: Fix problematic case where system-out tag occured twice per testcase
  element in the XML report. Thanks kkoukiou_ for the PR.

  (2137). Thanks to gst for the report and mbyt_ for the PR.

  Thanks to bluetech.

• --override-ini now correctly overrides some fundamental options like python_files (2238).

• Fix trailing whitespace in console output if no .ini file presented (2281). Thanks fbjorn for the PR.

  being an instance of PyobjMixin, and can therefore apply to tests not
  collected by the built-in python test collector. Thanks barneygale_ for the
  PR.
