bug#14608: [feature request] option `--' for signifying end of options and beginning of the list of file names

[niku <vaibhav.niku@gmail.com>]

Dear Emacs developers,

Many GNU and *nix world programs have the option `--' to mean end of
the list of options, and beginning of the list of file names.
Examples:
vim -- file1.txt file2.txt
rm -- file.txt

This has the added benefit that filenames with hyphen in the beginning
of the name can be
processed seamlessly, and without a security risk.

Please consider adding the option to Emacs too. In Emacs, it works
already in the X environment,
but not in Linux console. (And it is not documented.) This will

(i) add a useful and intuitive option to Emacs.
(ii) it will displace nothing: there is no such option in Emacs, or in
any proposed feature request. Further, this undocumented feature
already works under the X environment.
(iii) I imagine adding it will not be too much work for the developers!
(i) make it consistent with other text editors, so script writers will
not have to create a separate
case for Emacs.

Thanks for your consideration.

This discussion arose as a result of a discussion here:

Yours faithfully,
~Vaibhav.
