vim-patch:9.0.0423: "for" and "while" not recognized after :vim9cmd and :legacy (#24825) 
Problem:    "for" and "while" not recognized after :vim9cmd and :legacy.
            (Emanuele Torre)
Solution:   Recognize all the command modifiers. (closes vim/vim#11087)
            Add a test to check the list of modifiers.
