- shortened looping logic in search_packages_info - added logic to find installed files for .dist-info's - Seemed to be off-by-one error for assert exceptions in test_show_with_files_not_found - changed ..._with_files_not_found to use an editable install for being unlistable - added test to assert a wheel's files are now listed :D
