bug#1025: 23.0.60; file name completion fails in *shell* buffer

[Peter Dyballa]

Hello!

When I write in *shell* buffer the command to launch an elderly  
version of an Emacs application in Mac OS X to pass some arguments to  
it, I use file name completion. I have to do it in steps. I start  
with <SPC> that GNU Emacs does not complain when I later try file  
name completion and write then "/App" <TAB> that it becomes / 
Applications/. I add "Aqu" and <TAB>. The path name is now expanded  
to "/Applications/AquaEmacs" with a few choices which are shown in a  
*Completions* buffer upon next TAB press:

	Click <mouse-2> on a completion to select it.
	In this buffer, type RET to select the completion near point.
	
	Possible completions are:
	AquaEmacs-2a.app/ 	AquaEmacs-bundle.app/ 	AquaEmacs-pre3.app/
	AquaEmacs-zuvor.app/ 	AquaEmacs.app/ 	AquaEmacs\ 8.0-rc5.app/

I select the last item, i.e. "AquaEmacs\ 8.0-rc5.app/" so that the  
command line now shows "/Applications/AquaEmacs\ 8.0-rc5.app/". This  
directory has only one member: "Contents". So I hit <TAB> and see: "/ 
Applications/AquaEmacs 8.0-rc5.app/Contents/". Great! The auxiliary  
backslashes are removed from the previously ugly view. This directory  
has a few members. To make a choice I hit again <TAB>. In *shell*  
buffer nothing happens, a beep sounds, and a *Backtrace* buffer opens:

	Debugger entered--Lisp error: (file-error "Opening directory" "no  
such file or directory" "/Users/pete/8.0-rc5.app/Contents/")
	  file-name-completion("" "/Users/pete/8.0-rc5.app/Contents/")
	  comint-dynamic-complete-as-filename()
	  shell-dynamic-complete-filename()
	  run-hook-with-args-until-success(shell-dynamic-complete-filename)
	  comint-dynamic-complete()
	  call-interactively(comint-dynamic-complete nil nil)

So it seems that the decision to remove the backslashes wasn't so  
clever ...
