patch 9.2.0702: :windo and :tabdo create an extra window with 'winfixbuf'
Problem: With 'winfixbuf' set in the current window, :windo and :tabdo
create an extra split window, even though they only visit
existing windows/tabpages and don't change the current
window's buffer (Collin Kennedy)
Solution: Skip the 'winfixbuf' escape in ex_listdo() for :windo and
:tabdo (ShivaPriyanShanmuga)
fixes: #14301
closes: #20600
