Message:

	Modified the behavior of last so that "> >" will clear the screen.
	The new behavior of last is:
	      Moves the pointer to the last message in the view.
	      If we are already at the last message in the view,
	      blanks the screen and moves just past the end of the view
	      so that new messages will appear starting at the top
	      of the screen.
	Fixed a typo in the help for smartzpunt.
	Fixed functions to handle curmsg being past the end of the view.
