Attached is an updated version of a patch that adds a 'titlechanged'
hook for when the current window's title changes, suitable for keeping
the current window's title in a dzen status bar. The old one didn't
work against the current source (since the newwindow hook was
committed); this one also includes an appropriate doc patch.
