Implementing the behaviour looks like the easier part, it is just a bit 
of fiddling in [NSMenu update]. The hard bit is to find out, what should 
be done in all cases. The different cases I see are:

The popup button cell has an action or not. This may correspond to a 
target or not and in the first case the target may report the action as 
valid. And the same for the menu item.

As a short cut we may expect that the menu item allways takes preference 
before the popup button cell. Also, if an action is defined, no target 
means disabled item. Both hypotheses need checking.

If all this is true, than the change you suggest would mean, that if 
both the item and the popup don't have an action, the item is enabled. 
If you are able to confirm this, I will put in the simple bug fix.
