Subject: When starting Cocoa Emacs, two frames are opened under some conditions

Hi,

Under some conditions, Emacs 23.2.1 opens two frames under Mac OS X.
For instance, with

prunille:~> /Applications/MacPorts/Emacs.app/Contents/MacOS/Emacs tmp/foo

a first frame "foo" is opened, then a second one is automatically
opened. The buffer name of this second frame is foo<2> and the title
is "/Users/vinc17/tmp/tmp/foo". This occurs even without a .emacs
file. Note also that the path /Users/vinc17/tmp/tmp/foo doesn't exist
(the real path is /Users/vinc17/tmp/foo). Without a .emacs file, the
*Messages* buffer just contains:

For information about GNU Emacs and the GNU system, type C-h C-a.
Use M-x make-directory RET RET to create the directory and its parents

This problem doesn't occur with:

prunille:~> /Applications/MacPorts/Emacs.app/Contents/MacOS/Emacs -q tmp/foo
prunille:~> /Applications/MacPorts/Emacs.app/Contents/MacOS/Emacs ~/tmp/foo
prunille:~tmp> /Applications/MacPorts/Emacs.app/Contents/MacOS/Emacs foo
prunille:~> open -a Emacs.app tmp/foo

In particular, this is quite strange that the "-q" option makes a
difference without a .emacs file.

Yes, the patch works for me.
