Re: Proposal: emacs -Q option

[Steven Tamm]

-psn or "Process Serial Number" is used on OSX to provide a bridge 
between the old Classic Process Manager and the BSD core.  This number 
shouldn't be accessed through the command line, but instead through a 
Carbon function call.
It should be ignored whenever possible (i.e. not in cmdargs.texi nor in 
--help), and if it wasn't available to the Emacs process itself (i.e. 
removed from the command line arguments), that would probably be a good 
thing.  Mostly because it cannot be specified by the user without 
causing... problems.
