...em when npm installing from windows

Its funny, the ^ in the minimatch dependency worked fine on my Mac but was causing a problem when I did an npm install in windows.

Here is a link to the issue I just reported:

Thanks so much for looking into this!  It is causing a problem today when I tried to npm install the grunt-contrib-jshint  on my coworkers windows box.
