Isn't the state of each word, once expanded, saved somewhere?
_complete_debug doesn't show anything interested.

By reading the manual, I'm not completely sure about the relationship
between match-words-by-style and match-word-context.

Just to reiterate, imagine expanding a path. But the expansion needs to
be altered for some reason. I often kill the last path component.

If the context of the completer was saved, I could say that *only*
expanded paths get splitted by '/', and not other arguments.

I'm not sure it would be "terrific" in practical terms, as for this kind
of interaction you need to play around and see if it's worth the
tweaking.
