It depends on the toolkit you use I guess.  With Lucid the effect is 
awful, see attached screenshots.

Perhaps we're looking at different Text menus, but I see five entries in 
that menu, two of which have a checkbox.

It's what happens elsewhere in that menu and in others, some items are 
disabled or enabled depending on whether their corresponding action can be 
performed, but none disappear when their corresponding action cannot be 
performed, at least not in the standard menus.

What do you mean?  Problem 1 above is the appearance of the checkbox, 
problem 2 about the fact that a menu item appears and disappears, problem 
3 about the number of menu entries.  These are three separate things.

My conclusion so far is that the most reasonable compromise would be to 
use the second patch (attached again).
