patch 9.0.1065: a shell command switching screens may still have a problem

Problem:    A shell command switching screens may still have a problem with
            the kitty keyboard protocol.
Solution:   Disable the kitty keyboard protocol both in the current and the
            alternate screen, if there are indications it might be needed.
            (issue #11705)  Also fix naming.
