Yeah, isn't that a bit too intrusive if done generally?  If we display
these markers very visibly, then buffers where they are legitimately
used would be kinda ugly.  And I don't think users would necessarily
know that the URL is displayed the wrong way around just because there's
an ugly control character displayed before or after the URL...

When hitting RET on an URL, the function that handles that could ask
Emacs "is the http://domain.com bit displayed RTL or LTR"?  If it's RTL,
then that function could "are you sure?" the user.
