New problem with py-temp-directory

[Richard Stanton]

Using r911 under OS X, I have TMPDIR set to a valid directory, yet when I run a python script under python-mode then run

C-h v py-temp-directory

I get the result nil, which seems odd.

I tried running the following code, taken from python-mode.el, in my *scratch* buffer:

(defun ok '(lambda (x)
               (and x
                    (setq x (expand-file-name x)) ; always true
                    (file-directory-p x)
                    (file-writable-p x)
                    x)))

(defun fff ()
  "RHS test of temp-dir code"
    (or (funcall ok py-temp-directory)
        (funcall ok (getenv "TMPDIR"))
        (funcall ok (getenv "TEMP/TMP"))
        (funcall ok "/usr/tmp")
        (funcall ok "/tmp")
        (funcall ok "/var/tmp")
        (and (eq system-type 'darwin)
             (funcall ok "/var/folders"))
        (and (or (eq system-type 'ms-dos)(eq system-type 'ms-dos)(eq system-type 'windows-nt))
             (funcall ok (concat "c:" (py-separator-char) "Users" )))
    (error
     "Couldn't find a usable temp directory -- set `py-temp-directory'")))

(fff)
"/var/folders/zf/bgjm4tvs3wv_6q7_6z3b2nx00000gn/T/"

Note that this produces the desired result.
