No it doesn't fix it. The problem is: with my setup if I type `ls si'
I get the line `ls sig.' with the cursor on the `g'. If I now type TAB
(with automenu set) it immediately starts menu-completion (or, in my
case, menu-selection -- which is even worse in this case). Instead I
just want it to move the cursor on the dot, where normal completion
would place it.

That's what `compconf predict_cursor=key' tries to achieve. The `!',
btw, is somewhat irritating anyway -- if it is interpreted as a
history reference. Well, it isn't irritating if you know why it
happens, but probably not what one wants. (But the point of this
prediction thing is probably trying to make bang-hist expressions
superfluous, I'm just used to using them...)

This is similar to my automenu problem. What we need is a way to
control normal completion (not the one called by prediction)
works. For your problem we could simply use:
[[ -n $hasspace && compstate[nmatches] -eq 1 ]] &&
(Tricky, ain't it?)
For my problem we could use something like:
[[ $LASTWIDGET != $WIDGET ]] && compstate[insert]=unambiguous
(I'm not completely sure that his would work...)

I use `^P' for -on and `^P^P' for -off.

But then we have to test the special value `0', too.
