Subject: [PATCH] Use a temporary file for storing unencrypted files while
 editing

Origin: https://github.com/rails/rails/commit/a21d6edf35a60383dfa6c4da49e4b1aef5f00731

When we're editing the contents of encrypted files, we should use the
`Tempfile` class because it creates temporary files with restrictive
permissions.  This prevents other users on the same system from reading
the contents of those files while the user is editing them.
