Issue:
Since setuptools 28.5.0, a "global-exclude .pyc" no longer matches .pyc files
Since commit bb45468d27615c2ce9f9c9757a367c44d6ee80d2, if a project's MANIFEST.in contains ``global-exclude .py[co]``, the archive generated with ``python setup.py sdist`` will still contain all ``.pyc`` / ``.pyo`` files.

The test below shows that this line worked in setuptools 28.4.0, and broke in setuptools 28.5.0.

I'm not sure whether this can be considered a bug: the previous implementation looked up patterns without any anchoring, whereas the new one forces users to explicitly include wildcards in their ``MANIFEST.in``.
However, I think this change should have been mentioned in the version Changelog.

Pull request:
Fix #849 global-exclude globbing
After #764, `global-exclude .pyc` no longer excluded `.pyc` files. This fixes that regression, and adds a test for this behaviour.

Fixes #849.
