`grep -P` gives access to the PCRE matching engine, which is nice, however, the version of grep shipped on many BSD systems (including Darwin) does not have this flag. Currently, `grep -P` was being used in the `_includes()` test helper. For cross platform compatibility in tests, do not rely upon this option. Luckily, all existing tests seem to work fine without it already!
