Wow, that's some pretty easy, straight-forward code. ;-)

It looks to me that I could copy the `completion-pcm-all-completions'
function and add a FILTER for deleting the entries consisting of too
many words to the call to `completion-pcm--find-all-completions'.  I'll
try that as soon as I find some time...

Maybe.

A related question: Is the canonical way to use different completion
styles depending on what to complete advising the relevant functions?
Currently, I use that:

--8<---------------cut here---------------start------------->8---
(setq completion-styles '(basic initials partial-completion)
      read-buffer-completion-ignore-case t)

(defadvice read-buffer (around th-read-buffer-set-substring-completion activate)
  "Enable substring completion when reading buffers."
  (let ((completion-styles '(basic substring)))
    ad-do-it))
--8<---------------cut here---------------end--------------->8---

Works good and feels like IDO, especially in combination with icomplete.
So thanks a lot for all your great work on the completion facilities. :-)
