bug#11718: 24.1.50; `all-completions' returns results with wrong case

[Michael Heerdegen <michael_heerdegen@web.de>]

Hello,

I use emacs-snapshot on Debian Linux ("GNU Emacs 24.1.50.1
(i486-pc-linux-gnu, GTK+ Version 3.4.2)\n of 2012-06-14 on zelenka,
modified by Debian").

I have a directory "~/Trash".  If I eval

   (let ((completion-ignore-case t))
     (all-completions "~/tra" 'read-file-name-internal 
                      'file-exists-p nil))

in emacs -Q, I get

  (#("trash/" 0 3 (face completions-common-part)))

Note the wrong lower case of the result.  In Emacs 23, however, I get

  ("Trash/")

that is, the right case.

Not sure if this is really a bug, but, at least, this change in
behavior is documented nowhere, and it causes a completion bug in
Icicles.


Thanks,

Michael.
