This function synchronously retrieves the data specified by @var{url},
and returns a buffer containing the data. The return value is
@code{nil} if there is no data associated with the URL (as is the case
for @code{dired}, @code{info}, and @code{mailto} URLs).

+If @var{silent} is non-@code{nil}, don't do any messaging while
+retrieving. If @var{inhibit-cookies} is non-@code{nil}, refuse to
+store cookies. If @var{timeout} is passed, it should be a number that
+says (in seconds) how long to wait for a response before giving up.
