/**
* 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).
