python-check-manifest-0.37-bp153.1.20

- update to version 0.37:
  * Drop Python 3.3 support.
  * Support packages using setuptools_scm (#68).
  * Note that setuptools_scm usually makes MANIFEST.in files obsolete.
    Having one is helpful only if you intend to build an sdist and then
    use that sdist to perform further builds, instead of building from
    a source checkout.

- update to version 0.36:
  * Handle empty VCS repositories more gracefully (#84).
