zeertzjq c1fa8789c1 vim-patch:9.1.0112: Remove undo information, when cleaning quickfix buffer
Problem:  When the quickfix buffer has been modified an autocommand
          may invalidate the undo stack (kawarimidoll)
Solution: When clearing the quickfix buffer, also wipe the undo stack

fixes: vim/vim#13905
closes: vim/vim#13928
