RE: GUD mode bug

[Joonhwan Lee]

Greate. your new string->strings func works well.  I'm elisp beginner and had spent a quite long time in 
writing the equivalent routine but failed, though.

Anyway, Here's another issue introduced. 

In gud-common-init, there is routine extracting the name of debuggee.
It seems to me that 

;; Extract the file name from WORDS
     ;; and put t in its place.
     ;; Later on we will put the modified file name arg back there.
     (file-word (let ((w (cdr words)))
              (while (and w (= ?- (aref (car w) 0)))
            (setq w (cdr w)))
              (and w
               (prog1 (car w)
                 (setcar w t)))))

is too naive. 

In my previous example, the name of debuggee should be the last one(path-to-the-debuggee)
But with above code, gud thought it is "runargs -simu; run" 'cause it doesn't start with hypen.

btw, It seems to me that it may be a little hard to introduce a general way of extracting the name of debuggee. 
Any idea? maybe user-configurable predicator for this?

I've fixed this in the CVS repository at Savannah.  If you can build from there
can you tell me if it is fixed now.  Failing that, please apply the patch below
to gud.el, evaluate the function string->strings and try it from there.  Does
that work now?

(defun string->strings (string &optional separator)
  "Split the STRING into a list of strings.

  (string->strings (strings->string strs)) == strs
