I invoke 'M-x shell RET'. Tcsh is my login shell. No ~/.tcshrc file  
exists. For tests I renamed ~/.cshrc. ~/.emacs_tcsh has this contents  
to have a rather clean environment:

	foreach ENV (`env | awk -F= '{print $1}'`)
	  unsetenv $ENV
	end
	echo -n "Environment deleted. Proof: the env command's output..."
	env

symlinks user_tcsh_initdir default_tcsh_initdir dir tcsh_initdir  
framework_path histfile history host shlvl
	set

When I type in *shell* buffer 'ls -l /usr/ TAB' and pick 'bin/' from  
the *Completions* window, the text in *shell* I had already is  
substituted to 'bin/'. The *Completions* window shows:

	Click <mouse-2> on a completion to select it.
	In this buffer, type RET to select the completion near point.
	
	Possible completions are:
	../           ./          X11-vorher/  X11/         X11R6/           
X11R7.1/

local/
	sbin/         share/      standalone/  texbin

'env' shows nothing, 'set' shows these:

	_	
	argv	()
	cwd	/Users/pete
	dirstack	/Users/pete
	gid	501
	group	pete

The same behaviour shows bash, that I start with 'bash -li' or Korn  
shell that I start with a simple 'ksh' or zsh that I start with a  
simple 'zsh' or another bash ... In *terminal* buffer I don't see the  
same. In *eshell* I can try choose from *Completions* but get told in  
echo-area: "Text is read-only."


In this elder version of GNU Emacs 23.0.60 file name completion works  
fine in *shell*:

It doesn't work completely, meanwhile. A C-x d leads to an error:

	Debugger entered--Lisp error: (void-function completion-table-in-turn)
	  completion-table-in-turn((lambda (&rest --cl-rest--) (apply #[...

	  call-interactively(dired nil nil)

and *Messages* contains:

	Note, built-in variable `word-wrap' not bound
	Note, built-in variable `shift-select-mode' not bound
	Note, built-in variable `delete-by-moving-to-trash' not bound

but it still proves that shell-mode once worked correctly in GNU  
Emacs 23.0.60.

It isn't pollution that's harming the environment. It's the  
impurities in our air and water that are doing it.

I don't see the problem on latest CVS.  Does it still happen for you?

It seems to have gone ...
