bug#704: 23.0.60; buggy file name completion in *shell* buffer

[Peter Dyballa]

Hello!

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..."

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/
	X11R7.2/      bin/        include/     lib/         libexec/         
local/
        sbin/         share/      standalone/  texbin

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

        _       
        argv    ()
        cwd     /Users/pete
        dirstack        /Users/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 #[...

(quote --default--) --cl-rest--)) read-file-name-internal)
          dired-read-dir-and-switches("")
          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
        Note, built-in variable `read-buffer-completion-ignore-case' not bound
        Note, built-in variable `underline-minimum-offset' 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.
