The Screen Status Line

In my ~/.screenrc, I have:
shell -$SHELL
startup_message off
defscrollback 10000
activity ''
hardstatus alwayslastline '%{= wk}%?%-Lw%?%{r}
             (%{k}%n*%f%t%?(%u)%?%{r})
             %{k}%?%+Lw%?%?%= %m/%d %C%A'
Note: The hardstatus line has no spaces or newlines in my file.
Refer to screen(1) for more information.
