[OS X Emacs] NeXT emacs sets $DISPLAY

[xah lee]

i don't have the file “~/.MacOSX/environment.plist”.

just to be more complete and clear, here's the symptom:

1. start NeXT emacs by clicking its icon in Finder.
2. Type “M-! echo $DISPLAY”
3. it shows xah5.local

The verison i'm using is
GNU Emacs 23.0.60.1 (powerpc-apple-darwin7.9.0, *Step 9.0rc3) of  
2007-11-24 on applecore.inf.ed.ac.uk

---------
Now, start it from Terminal with:

/Applications/Emacs2.app/Contents/MacOS/Emacs -q &

(i named it Emacs2.app since i already have Carbon emacs as Emacs.app)

same thing happens.

------------

This doesn't happen with Carbon emacs, either starting from icon or  
from Terminal with -q.

----------------------------

here's the complete env var from “M-! env” when starting from  
terminal
/Applications/Emacs2.app/Contents/MacOS/Emacs -q &

Hi,

Could be a stale "~/.MacOSX/environment.plist".  Do a search on this
list for discussions.  You can either run
/path/to/Emacs.app/Contents/MacOS/bin/mac-fix-env , or run M-x
ns-grabenv (or run that in your .emacs) to fix this problem.  This is
covered in the manual (first entry under Help menu).

I'm not sure why you don't experience the problem under Carbon emacs.
Aquamacs does the equivalent of ns-grabenv on startup, maybe plain
Carbon does now too?
