Christian Clason bdfea2a891 vim-patch:9.1.0001: when closing window, wincmd p may fail
Avoid `prevwin == curwin` when closing `curwin`

Problem:  When closing the current window (or when moving it to a tabpage), the
          previous window may refer to the new current window
          (`winnr() == winnr('#')`) if that window is selected as the
          new current window.

Solution: Set `prevwin = NULL` when switching away from an invalid `curwin` and
          the target window was the `prevwin`.
          (Sean Dewar)
