   // Note: As far I can tell, escaping glob syntax has _never_ worked on
   // Windows. In Elm, needing to escape glob syntax should be very rare, since
   // Elm file paths must match the module name (letters only). So it’s probably
   // more worth supporting `some\folder\*Test.elm` rather than escaping.
