The helpClose function is used to call UpdateScreen on MessageViewer,
which has the effect of invalidating and redrawing the message view.
This logic is redundant with the addition of tcell-term and the main
event loop.
Remove the helpClose calls. Remove the UpdateScreen methods from
messageviewer: those functions are only used by the helpClose function.
