This is not possible in a simple way as all output goes to STDERR by
default. That is historically designed so that -O- works as expected
(without mixing page contents with wget status messages).

We can't change this without braking backwards compatibility. Well
someone could add another option to deal with it.

For Wget2 we decided to write normal output messages to STDOUT while
error messages go to STDERR. This would be in line with standard *nix tools.
So with Wget2 you have to combine -q and -O- if you *don't* want content
and messages being mixed on STDOUT.
