pyramid.events.subscriber with empty events list does not behave as documented

[xrotwang]

This may be just a documentation bug, but reading
"When the subscriber decorator is used without passing an arguments, the function it decorates is called for every event sent"
made me expect something that did not happen:

from pyramid.events import subscriber, NewRequest
from pyramid.config import Configurator

@subscriber()
def mysubscriber(event):
    print event

@subscriber(NewRequest)
def s(event):
    print event

if __name__ == "__main__":
    from waitress import serve
    config = Configurator()
    config.scan(__name__)
    serve(config.make_wsgi_app())

upon requesting http://localhost:8080 subscriber s will get notified, but mysubscriber won't.

confirmed, @mcdonc will have to answer whether it's a docs bug or implementation bug. There are no unit test for this case that I can find.

Thank you!
