It seems to me that the issue here is that icomplete expects one 
to accept completions via C-j 
(`minibuffer-force-complete-and-exit`) rather than RET (which is 
bound to `minibuffer-exit`). i myself find this behaviour 
counterintuitive, and would prefer that RET also be bound to 
`minibuffer-force-complete-and-exit`, since i would still be able 
to exit the minibuffer via C-g. i wonder if there are people 
relying on RET being bound to `minibuffer-exit`?
