 // A component specifies the range of the part of the URL. The begin specifies
 // the index into the string of the first character of that component. The len
 // specifies the length of that component.
 //
 // This range does not include any special delimiter for that component, so
 // the scheme doesn't include the trailing colon, the username and password
 // don't include the @ and :, the port doesn't include the colon, the query
 // doesn't include the ?, and the ref doesn't include the #.

 // The exception is that the path *does* include the first /, since that's an
 // integral part of the path.

 // If the component is not present at all, begin will be 0 and len will be -1.

 //   http://foo/search    -> query = (0, -1)
 //   http://foo/search?   -> query = (18, 0)
