Changed behavior of `all-completions' wrt case - bug?

[Michael Heerdegen]

Hello,

I use emacs on Debian Linux.

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 (Emacs 24.1.50.1), I get

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

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

  ("Trash/")

that is, the right case.

Is this change in the behavior of `all-completions' a bug?  I don't know
if this causes any harm in vanilla Emacs - however, there is a related
completion bug in Icicles.


Thanks,

Michael.
