You have a valid point, although I don't see the disadvantage of
allowing closing braces inside URLs, but I guess it should correctly
identify URLs like `(http://www.example.com/foo(bar))baz' as
`http://www.example.com/foo(bar)'.

Unfortunately I tried your solution with `re-builder' but it always
stop recognizing the URL at a closing parentheses. Could you verify if
it is working there for you?
