-r doesn't work in combination with -O - and a pipe

[Pekar]

-r doesn't work in combination with -O - (and pipe): 

wget -q -O - http://www.web.de |wc -l
709

wget -r -q -O - http://www.web.de |wc -l
709


wget --version
GNU Wget 1.10.2

please tell whether its a bug or I'm just doing something wrong, and if
it is - are there some working versions of wget in such a combination of
options?

thank you
Z. Pekar
