Subject: partial-completion-mode and completion-ignore-case combine to make 'read-file-name return a subdirectory when user enters the parent

scenario:  you have a directory (/scratch2/rfn-bug) that contains some number of files, and one sub-directory (/scratch2/rfn-bug/frog).
You are prompted for a file name via 'read-file-name, you enter "/scratch2/rfn-bug" and that is properly returned, you enter "/scratch2/rfn-bug/" and what is returned is "/scratch2/rfn-bug/frog"

To reproduce:

in a shell:
  mkdir /scratch2/rfn-bug
  touch /scratch2/rfn-bug/a
  touch /scratch2/rfn-bug/b
  mkdir /scratch2/rfn-bug/frog

Run emacs, and then evaluate:

   (setq read-file-name-completion-ignore-case t)
   (require 'complete)
   (partial-completion-mode t)
   (read-file-name prompt dir dir 'must-match nil 'file-directory-p)

When you enter "/scratch2/rfn-bug", you'll get back "/scratch2/rfn-bug"
When you enter "/scratch2/rfn-bug/", you'll get back "/scratch2/rfn-bug/frog"

If read-file-name-completion-ignore-case is nil, this problem does not happen.
If there are more than one subdirectory, this problem does not happen.
If the single subdirectory is a link, you get the same behavior.
Running on linux (as seen below).

I built this version of Emacs myself, but did nothing custom, just the
standard ./configure, gmake, gmake install.  This bug was reproduced running 
emacs w/out an initialization file.



thanks,

TJ

I've checked in a fix into CVS.  Thanks for the bug report.
