OK, this is a simple patch now which allows for inputting spaces in  
filenames in the minibuffer, while keeping the binding of space to  
minibuffer-complete-word in other contexts. It introduces a new  
keymap, minibuffer-local-filename-completion-map.

	* commands.h (Vminibuffer_local_filename_completion_map):
	declare a new keymap for minibuffer completion in case of filenames.
	* keymap.c (syms_of_keymap): Declare (Lisp) and make new keymap.
	* minibuf.c (completing-read): Use a new keymap when deadling with
	filenames.
	(keys_of_minibuf): initialize the new keymap.
	

for etc/NEWS:

** Minibuffer changes:

*** For filenames, Space is not bound to completion any longer
Filenames with spaces can be input intuitively with the space bar now,
space is not bound to `minibuffer-complete-word' any longer.
A new key map minibuffer-local-filename-completion-map applies whenever
a file name is prompted for.
