py-coverage: updated to 4.4.2

Version 4.4.2:

- Support for Python 3.7.  In some cases, class and module docstrings are no
  longer counted in statement totals, which could slightly change your total
  results.

- Specifying both ``--source`` and ``--include`` no longer silently ignores the
  include setting, instead it displays a warning. Thanks, Loïc Dachary.  Closes
  `issue 265`_ and `issue 101`_.

- Fixed a race condition when saving data and multiple threads are tracing
  (`issue 581`_). It could produce a "dictionary changed size during \ 
iteration"
  RuntimeError.  I believe this mostly but not entirely fixes the race
  condition.  A true fix would likely be too expensive.

- Configuration values which are file paths will now apply tilde-expansion,
  closing `issue 589`_.

- Now secondary config files like tox.ini and setup.cfg can be specified
  explicitly, and prefixed sections like `[coverage:run]` will be read. Fixes
  `issue 588`_.

- Be more flexible about the command name displayed by help, fixing
  `issue 600`_.
