 Log Message:
 Back out incorrect fix for PR 53617 and fix it in a different way.
 Keep track of the cursor location, if getch is called without a refresh
 and without pending updates (dirty windows) then move the cursor to the
 correct location directly.  Doing this prevents unnecessary refreshes.
