Subject: 23.0.60; comint-dynamic-complete should correct the case of the completed name 
Date: Fri, 27 Jun 2008 09:22:09 -0700

I've got read-file-name-completion-ignore-case set to t, and in a
*shell* buffer I just typed

        cd art TAB

Now, there's a subdirectory called Artemis2, and so the TAB caused
completion, so that my input line now looks like

        $ cd artemis2/

The problem, though, is that the "cd" command fails, because the file
system is case-sensitive, and thus "artemis2" is not the same as
"Artemis2".  I wish TAB had instead made my input line look like

        $ cd Artemis2/

Curiously, completion works as I'd expect in the minibuffer.  That is,
if I type

        M-x cd RET ~/art TAB

I see

        Change default directory: ~/Artemis2/

which is exactly right.

I've checked in a fix.  Could you give current CVS trunk a test?
