This is a very common convention for command-line tools. I don't think
this is a bug. Use --print-pid=1, --print-address=1 (making the default
- in this case stdout - explicit) instead of the form with no argument.

Arguably, command-line options with an optional argument are a design
flaw - each command-line option should either have a mandatory argument
or no argument - but for dbus-daemon it's too late, since we already
have --print-address[=DESCRIPTOR] and --print-pid[=DESCRIPTOR].
