bug#4640: 23.1.50; GNU Emacs does not follow geometry settings from command line

Hello!

A French brought this problem up in help-gnu-emacs for GNU Emacs  
23.1. The bug seems to exist also in the CVS version. Launched as

	src/emacs -Q -g 20x20+200+200 &

the frame is wider than thought and xwininfo then shows:

	  Corners:  +202+228  -930+228  -930-350  +202-350
	  -geometry 38x20+200+200

A second frame, from C-x 5 2, is put at the right edge of my screen:

	  Corners:  +1244+176  -14+176  -14-402  +1244-402
	  -geometry 20x20-12+148


My window manager is Blackbox 0.65.0 : (c) 2001 - 2002 Sean 'Shaleh'  
Perry
			    1997 - 2000, 2002 Brad Hughes

My xserver is X11 1.1.3 - XFree86 4.4.0, provided by Apple.

GNU Emacs 23.1.50 uses more up-to-date X libraries from outside (from  
the MacPorts project).
