> There are a lot of code in Path to get start position after skipping drive specifier,
like:
> {code}
>     int start = hasWindowsDrive(uri.getPath()) ? 3 : 0;
> {code}
> Also there is a minor bug in mergePaths:
> mergePath("/", "/foo") will yield Path("//foo") which will be parsed as uri authority,
not path.
