I don't think it can: some of the options are specific to the window
system you are using, and are not parsed until the window system is
detected and its support loaded at run time.

If you look closely at what "emacs --help" print, you will see that it
doesn't show all the options Emacs can accept.  For example, -rv and
--title are not shown, and neither are --background-color or --iconic.
