I've tracked down a problem with partial-completion-mode and tramp
that has been bugging me for a while.

Behaviour with emacs -Q:

    C-x C-f ~/.emacs// TAB    =>    /    [after minibuffer prompt]
    C-x C-f ~/.emacs/ TAB     =>    "not a directory error"

Completion still works:

    C-x C-f ~/.emacs// TAB    =>    /

Now evaluate:

    (progn
      (require 'tramp)
      (partial-completion-mode))

This works:

    C-x C-f ~/.emacs// TAB    =>    /

    (symbol-function 'substitute-in-file-name) =>
        #<subr substitute-in-file-name>

This causes a "no such file or directory" error:

    C-x C-f ~/.emacs/ TAB     =>    /home/matt/*.emacs*/

and:

    (symbol-function 'substitute-in-file-name) => #<subr identity>

Completion that worked above now fails:

    C-x C-f ~/.emacs// TAB    =>    /home/matt/*.emacs*/*/

since substitute-in-file-name has been clobbered. Find attached a
simple fix. Thanks,

Matt
