I should have added that for the value is nil also for plain `C-u', that is, `C-u' not followed by anything. But 4 is the value for plain `C-u C-u' etc. IOW: If `C-u' is followed by another key then the value is 4. If `C-u' is not followed by another key then the value is nil.

In the original frame, access menu Foo and submenu Bar, using (1) no prefix arg, (2) a prefix arg introduced using `C-u', and (3) a prefix arg introduced in another way, such as `M-2'. The actual prefix arg you give is not employed in the :visible code (same thing for :enable). Instead: * For no prefix arg given, or for any prefix arg given other than by using explicit `C-u', the value used by :visible is nil. * For a prefix arg given using explicit `C-u', the value used by :visible is 4. That is, in the former case you see always "PP: nil" output, and for the latter you see always "PP: 4" output. This means that you cannot use the prefix arg in a menu-item test. This should not be the case. (This problem is not new.)
