[Message part 3 (text/plain, inline)]

I'm not sure if this is a Mac problem, or an Emacs 25 problem, but it occurs
with the latest emacs-25 on OS X 10.10:

    M-: (make-temp-name "index.magit.") RET

Will report the error:

    Cannot create temporary name for prefix: Bad file descriptor, index.magit.

I discovered this because Magit 2.6 uses temporary files with such a name.
