Problem Description: In ex_mode, the default_grid.chars are not allocated, and subsequently,
the w_grid.target in curwin is not allocated to default_grid in update_screen. This leads to
a null pointer crash when the completion function is executed in ex_mode.

Solution: Set full_screen when in ex_mode to ensure that default_grid is allocated.

Instead cause some changes to screen state and use screen:expect().

Problem:  'shortmess' "F" flag doesn't work properly with 'autoread'
          (after 9.1.0154)
Solution: Hide the file info message instead of the warning dialog
          (zeertzjq)

Problem:  has('pythonx') always returns 1.
Solution: Make it the same as has('python3').

Problem:  Text is not redrawn with 'relativenumber' when only the 'statuscolumn' is redrawn after inserted lines.
Solution: Force a full redraw if statuscolumn width changed.

Problem:
`vim.lsp.util.rename()` deletes the buffers that are affected by
renaming. This has undesireable side effects. For example, when renaming
a directory, all buffers under that directory are deleted and windows
displaying those buffers are closed. Also, buffer options may change
after renaming.

Solution:
Rename the buffers with :saveas.

An alternative approach is to record all the relevant states and restore
it after renaming, but that seems to be more complex. In fact, the older
version was attempting to restore the states but only partially and
incorrectly.
