Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

In a shell, create a new directory and cd there.
> touch Foo Foobar
> emacs -Q

In the *scratch* buffer, type:
(setq read-file-name-completion-ignore-case t) C-j

M-x partial-completion-mode <return>

C-x C-f foo <tab>


I expected it to change "foo" to "Foo", because all possible
completions begin with "Foo".  That's what it does if you don't enable
partial-completion-mode.  But with partial-completion-mode enabled, it
stays "foo" and Emacs displays the list of possible completions.

If you type "b <tab>", it will change "foob" to "Foobar" (as expected).

This used to work in Emacs 21.3.1 (although there the variable is
completion-ignore-case instead).  I first noticed the bug a couple
months ago, but it's still present in the CVS HEAD version I compiled
yesterday.
