Yes, but it's not the completion-$curcontext, it's the zftp-one.

I considered i-complete-w to be a completion thing. And since in
completion it uses `:completion:incremental:...' I thought it would be 
easier to understand if it used that for all styles. But yes, now that 
I think of it again, maybe it it should look up its own styles with
`:incremental'. And the same for `:predict'. Because...

(although this was never really defined; maybe we should do that and
write it down in the devel-guide) ... something like: every `system'
uses its own prefix and whatever hierarchy it needs below that. Not a
very exact description, I'm afraid.

Right.

`:predict', I'd say.
