Subject: Fix NpmSpec prerelease-handling.

Thanks to Nathan Walters for spotting this.

Npm ranges with a `<X.Y.Z-P` component were not properly expanded:
they were converted to:
    <X.Y.0 || (>=X.Y.0 && <X.Y.Z-P && no-prerelease)

The correct expansion is:
    <X.Y.0 || (>=X.Y.0-* && <X.Y.Z-P)

Closes #86.
