the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

/Applications/Emacs.app/Contents/MacOS/Emacs -Q
M-x shell<RET>
ls /a<TAB>

Get "No match."  Should expand into "ls /Applications/"

Hi, sorry it's taken so long for someone to get back to you, but this
isn't Emacs's filename completion, this is the shells. Probably bash.
I'm afraid I can't help you with that.

[Message part 1 (text/plain, inline)]

So you're saying that

a) Emacs is deferring to Bash to do the completion in this case; and
b) bash is not ignoring case?

I find both of those hard to believe -- particularly since if I type "cd
doc" at a shell prompt that's not inside emacs, but is in a Terminal.app,
it does what I want (namely: completes to "cd Documents").

If a) is in fact correct, then I suppose Emacs is somehow starting the
shell differently than Terminal.app is.

OK, I think I was talking rubbish. It looks like Emacs does do the
completion.

(BTW, this bug looks like it's OS X specific in debbugs even though
it's reproducible in a GTK+ build on GNU/Linux too.)

For what it's worth, the problem doesn't repro in emacs23 (specifically,
this commit)
