  /**
   * Utility function to handle redirects returned from an action or loader.
   * Normally, a redirect "replaces" the navigation that triggered it.  So, for
   * example:
   *
   *  - user is on /a
   *  - user clicks a link to /b
   *  - loader for /b redirects to /c
   *
   * In a non-JS app the browser would track the in-flight navigation to /b and
   * then replace it with /c when it encountered the redirect response.  In
   * the end it would only ever update the URL bar with /c.
   *
   * In client-side routing using pushState/replaceState, we aim to emulate
   * this behavior and we also do not update history until the end of the
   * navigation (including processed redirects).  This means that we never
   * actually touch history until we've processed redirects, so we just use
   * the history action from the original navigation (PUSH or REPLACE).
