The decision isn't up to me, but I think this is a good idea. Here's a
patch that would update the documentation and hooks.py, as well as hooks.c.

FYI, if this patch is applied then anyone who's still trying to use a
goto_url_hook that expects a second argument will get a "Browser scripting
error" dialog box that says:

	An error occurred while running a Python script:

	TypeError: goto_url_hook() takes exactly 2 arguments (1 given)
