wmiir: do an explicit empty write when stdin is empty; this makes
it possible to for instance clear the bar by doing 'echo -n "" | wmiir write /bar/2/data'.
This makes sure that the bar is cleared when a window with no title is selected, instead of
retaining the title of the previously selected window.
