The `\//` sequences a bit ugly, which is why I had used the `%r` form when updating the `gems` regex awhile back.  You're right that it's inconsistent, though.  Do you think it's worth changing to use `%r{}` for all of these?  It would allow the dir separator to be used w/o needing it to be escaped.

Actually, I just remembered -- doesn't windows use `\` rather than `/`?  (It's been ~5 years since I last used windows...).  Maybe this should use `File::SEPARATOR`?
