 * format: [to, from, result]

 *  url.parse('f:/a') does not have a host
 *  url.resolve('f:/a', './/g') does not have a host because you have moved
 *  down to the g directory.  i.e. f:     //g, however when this url is parsed
 *  f:// will indicate that the host is g which is not the case.
 *  it is unclear to me how to keep this information from being lost
 *  it may be that a pathname of ////g should collapse to /g but this seems
 *  to be a lot of work for an edge case.  Right now I remove the test
