# When should_receive(message) is sent to any object, the Proxy sends
# respond_to?(message) to that object to see if the method should be proxied.
#
# If respond_to? itself is proxied, then when the Proxy sends respond_to?
# to the object, the proxy is invoked and responds yes (if so set in the spec).
# When the object does NOT actually respond to `message`, an exception is thrown
# when trying to proxy it.
#
# The fix was to keep track of whether `respond_to?` had been proxied and, if
# so, call the munged copy of `respond_to?` on the object.
