Yeah, that stymied me.  :)  I wasn't all that intent into diving into the C
source.  Though if it's well commented, I might take a look anyway.

Wonderful.  I was missing the compset bits, and while I might have
eventually stumbled on the first, I probably wouldn't have gotten the

The only thing remaining is to remove already-completed tokens, which I'm
doing with a simple loop over IPREFIX:

    for t in ${(s:,:)${IPREFIX//\\#\!/}}; do
        tokens=( ${tokens:#$t} )

before passing tokens on to compadd.  It looked like there wasn't any
special magic in _values that did this, but it's sufficiently poorly
commented that I wasn't sure exactly where this was happening.

You can't think of a fruit starting with "e" either, eh?  :)
