[h-e-w] Hard space and w32-downcase-file-names: crash

[Michel de Ruiter]

Hi all,

I have found a bug specific to NTEmacs. I'm not sure whether I should report it 
to bug-gnu-emacs instead. I thought I should try here first.

The easiest way to reproduce the crash is:
- start emacs -Q
- type M-:
- type (setq w32-downcase-file-names t)
- type RET
- type C-x C-f
- type C-q 2 4 0 RET
This shows the "Emacs Abort Dialog" ("A fatal error has occurred!").

I don't have gdb to further debug this.
This is GNU Emacs 24.0.96.1 (i386-mingw-nt6.1.7601) of 2012-04-29 on MARVIN, on 
Windows 7 Enterprise SP1 (x64, version 6.1.7601). I currently don't have time 
to try any newer build.

Anyone (Eli?), please take it from here.

Groente, Michel.
