  // pathname may have another "/" and pathname components added to it,

  // but some of the functions in FilePath will not handle that correctly. In
  // particular, RemoveTrailingPathSeparator() only removes one separator, and
  // it is called in CreateDirectoriesRecursively() assuming that it will change
  // a pathname from directory syntax (trailing separator) to filename syntax.
