Adam J. Stewart 1f303c9ac8 Don't add system paths to PATH (#3910) ... * Filter all system paths introduced by dependencies from PATH * Make sure path filtering works *even* for trailing slashes * Revert some of the changes to `filter_system_paths` * Yes, `bin64` is a real thing (sigh) * add tests: /usr, /usr/, /usr/local/../bin, etc. * Convert from rST to Google-style docstrings		2017-04-30 18:43:44 -07:00
