Uh, err... hm.

For now I don't know how to change it. This is an effect of
menucompletion being set. Without menucompletion, the other completion 
widgets get called all right. But with menucompletion and the ad-hoc
completion widget not behaving like `list-choices' or `delete-char-or-list',
the test in zle_tricky:759 keeps the next completion widget from being
called.

Hm. maybe if we move the test I removed zle_main.c to this place...

Could you play with it and tell me if this is better?
