Changelog:
==========
-When checking if a file mapping resolved to a file that exists, we weren't
considering files in .whl files. This is now fixed, closing issue 1511.
-File pattern rules were too strict, forbidding plus signs and curly braces
in directory and file names. This is now fixed, closing issue 1513.
-Unusual Unicode or control characters in source files could prevent reporting.
This is now fixed, closing issue 1512.
-The PyPy wheel now installs on PyPy 3.7, 3.8, and 3.9, closing issue 1510.
