the rc man page will not shed any light here.
looking at /rc/bin/window might, though.
you'll see that the command is executed by
just running $cmd where cmd is the arguments
given to window.  you want something that works
if typed at a shell prompt but doesn't do anything
that would cause parsing by rc before getting
into window.  in other words

window -m rc -c 'cat >>/tmp/out'
