ido.el reports possible completions wrongly

[Chris Moore]

Using this 2 line .emacs file:

  (require 'ido)
  (ido-mode t)

and with hundreds of files in /usr/bin/, including /usr/bin/gnuplot,
typing:

  C-x C-f / u s r / b i n / g n u p l o ?

shows me a message "There are no possible completions of what you have
typed", but hitting SPC or TAB goes on to complete it to gnuplot, as
expected.  Which typing the "gnuplo" part, I see "[Too big]" in the
minibuffer after the cursor.

Note also that immediately before typing the "g" in the above input,
the minibuffer displays:

  Find file: /usr/bin/{bin/ | sbin/}

suggesting that /usr/bin/ contains subdirectories called 'bin' and
'sbin' (which it doesn't).  Typing the '/' after 'bin' should have
made ido move on to the contents of the /usr/bin/ directory, but since
it's a big directory, it doesn't.
