bug#842: 23.0.60; find-file prompt is case sensitive on w32

[Lennart Borgman (gmail)]

Try for example

  C-x C-f cha TAB

in emacs/src.

This should be case insensitive on w32 since the file system is case
insensitive.

I don't see that. emacs -Q with:

In GNU Emacs 23.0.60.1 (i386-mingw-nt5.1.2600)
 of 2008-08-29 on LENNART-69DE564
Windowing system distributor `Microsoft Corp.', version 5.1.2600
configured using `configure --with-gcc (3.4) --no-opt --cflags -Ic:/g/include
-fno-crossjumping'

I dont' have a src directory, but I tried it in a directory with uppercase,
lowercase, and mixed case files, and C-x C-f is case insensitive.

HTH.

Strange, this should be the same binaries that I am using ...

Is it perhaps the first character that matters? I am trying in emacs/src
with

  C-x C-f c TAB

and there are some files beginning with "c" and some with "C".

But there are more problems of this kind. Trying in emacs/lisp

  C-x C-f CVS TAB

I get [complete but not unique] and CVS/ is shown as only alternative.
And when I use

  C-x C-f CV TAB

I get cvs-status.el. What do you get in these cases?

I believe this used to work for me.

Dunno - your lines above don't include "on LENNART-69DE564"; mine do.

For me it is completed to c:/.../lisp/cvs-status.el, with no minibuffer message.

Do you have another file (in the dir) that starts with "cvs"?

Same here - same as above, exactly.

Are you sure you're using -Q?

It is the same.

Ah, yes. You do not have that one so this was a bad test. (It is the CVS
directory, which is hidden.)

Maybe if you create a file named CVS and try again?

Yes, I am a bit tired, stressed, but ... ;-)

bug#842: 23.0.60; find-file prompt is case sensitive on w32

> Maybe if you create a file named CVS and try again?

Yes, I confirm that I see the same thing as you.

With files CVS and cvs-status.lisp present, C-x C-f CVS TAB and C-x C-f cvs TAB
both do as you said: They show the minibuffer message "Complete but not unique",
and a second TAB shows only the file name CVS, not both file names as possible
completions. Looks like a bug.

What is your value of `completion-ignored-extensions'? Mine includes ".elc". You
no doubt have a file cvs-status.elc, in addition to .el.

The default value. This is with "emacs -Q".

Try for example

This should be case insensitive on w32 since the file system is case
insensitive.
