Yep. However, even if I apply this patch to icomplete.el and also your
Tramp patch it doesn't complete method names like "/ss TAB". So this
cannot be the proper solution I believe.

And, beside of fido-vertical-mode, your Tramp patch hides the method
names at all. If I try

emacs -Q -l tramp --eval "(setq completion-styles '(flex basic))"

and apply then 'C-x C-f /ss TAB', it offers only the candidate '/sys/',
and nothing else. W/o your patch, there are the candidates

--8<---------------cut here---------------start------------->8---
Possible completions are:
sshfs:  ssh:
sshx:   sys/
--8<---------------cut here---------------end--------------->8---

Anyway, all our tests are mood. I would really appreciate if a
completion style author could chime in, and could investigate. I don't
say that there isn't an error in Tramp, but before I accept patches I
must understand what's up. And the proposed patch doesn't fix all cases
sufficiently (plus it violates the API, but this we have discussed
already in several rounds).

Best regards, Michael.
