Re: patch: push window to frame

Now that I have played around with this a bit, it seems like a really
great idea. Combined with pullwindow it would make working with many
frames much easier.

The names pushwindow and pullwindow seem good to me. Rebinding "l"
shouldn't be a
problem, in my experience it is rarely necessary but I don't know what's
the
policy for such things.

I have modified the pushwindow function to not crash when there
is either no window to reveal or I try to push an empty frame.
When there is no window to reveal, I think the most obvious solution is
to just swap the window, hence window_to_reveal = window_to_cover.
