patch 8.1.0698: clearing the window is used too often
Problem: Clearing the window is used too often, causing the command line
to be cleared when opening a tab. (Miroslav Ko?k?r)
Solution: Use NOT_VALID instead of CLEAR. (suggested by Jason Franklin,
closes #630) Also do this for a few other places where clearing
the screen isn't really needed.
