23.0.50; PC-do-completion should fix case if possible

In GNU Emacs 23.0.50.2 (i686-pc-linux-gnu, GTK+ Version 2.10.11), I do

  (setq read-file-name-completion-ignore-case t)
  (partial-completion-mode)

then type

  C-x C-f c

in a directory containing directory "Cat" and file "Cattle".  Normal
completion will correct the case of my "c", completing to "Cat",
matching the files.  Partial completion (complete.el) completes to
"cat", which is wrong.

Attached is a patch against the latest from CVS.
