Even when creating a file, GNU cp by default does not use 'chmod' to copy the file's permissions (12 bits). Instead, it merely creates the file with the permissions of the source as modified by the umask (9 bits). That is why it doesn't run into a problem in your setup. The proposed patch would cause GNU Emacs to act similarly, which is why I expect it to work for you.
