Emacs doesn't preserve the file access permission.

[Hiroshi Fujishima]

Hi, 

Editing a file with Emacs doesn't preserve the file's permission.

% mkdir temporally-working-directory
% cd temporally-working-directory
% umask
022
% touch x
% chmod 600 x
% ls -l
total 0
-rw-------  1 pooh staff 0 Jan  1 19:54 x
% emacs x
% ls -l
total 1
-rw-r--r--  1 pooh staff 21 Jan  1 19:55 x
-rw-------  1 pooh staff  0 Jan  1 19:54 x~

I expect ``-rw------- 1 pooh staff 21 Jan 1 19:55 x'', not
``-rw-r--r-- 1 pooh staff 21 Jan 1 19:55 x''.
