    - The next is handled by `with-temp-buffer':

    (defun Man-support-local-filenames ()
               ...
               (with-temp-buffer
                 (and (equal (condition-case nil
                                 (call-process manual-program nil t nil 
"--help")
                               (error nil))

In what sense does the use of `with-temp-buffer' "handle" this issue?
New buffers copy the default directory from the current buffer, and I
don't see any code in `with-temp-buffer' to ensure the default
directory exists.
