Of course additional let bindings are needed for every variable modified
by the call to url-handle-mode.  So you end up writing code that makes
assumptions about the inner working of url-handler-mode.
Maybe we may as well just add (cons url-handler-regexp
'url-file-handler) to file-name-handler-mode rather than call
url-handler-mode.
