No clue what this actually does.  It should at least be removed from --help
when HAVE_SHM is not defined.

IIRC this is only used for undumped Emacsen.  It's "for hackers only".

I guess they should both be added.

Maybe this one as well.

This is used internally by the session-manager code (i.e. X11-specific).

This looks very "not-for-user".

I suspect these were X11 specific.  Maybe they are also somewhat supported
under other platforms.  They should definitely be mentioned in --help and
in the Texinfo doc.  Maybe it would be worthwhile to add them to
cmdargs.texi.

This said, I really think the --help text should be generated more
dynamically to match the exact set of args accepted by the executed Emacs.
