[h-e-w] [EmacsW32-bug] Opening .patch/diff files

[Stephan Stahl]

I'd like to report a bug with .patch/diff files in EmacsW32
(http://www.ourcomments.org/Emacs/EmacsW32.html).  It works fine in the 
unpatched emacs variant..

When opening such a file i get stuck in a file-open prompt.  To reproduce:

runemacs -Q

eval the following (from my .emacs):
(when (require 'ido nil t)
  (customize-set-variable 'ido-everywhere t)
  (customize-set-variable 'ido-enabled 'both)
  (customize-set-variable 'ido-mode 'both))
(if (require 'which-func nil t)
    (customize-set-variable 'which-function-mode t))

Now opening a .diff/.patch file seems to try to open the original file and 
thanks to ido or
which-func it tries again and again and again, even when pressing C-g to get 
out of the prompt. 
This works fine in the unpatched variant so it must be due to the changes in 
EmacsW32.

Thanks in advance for any help.
