bug#590: emacsclient not working in Emacs.app

[Gilbert Harman]

Using intel iMac, OS 10.5.4, Emacs.app from CVS an hour or so ago,
with (server-start) in my .emacs.  In a separate terminal session
running alpine, I attempt to edit a mail message, which should open a
window in emacs.  Instead I am immediately returned to the terminal
session.  The error message there is:
-error 
Unknown&_command:&_/var/folders/X8/X8zFtrhsG5WoJEjIaN+OJU+++TI/&-Tmp&-/pico.543400

No relevant message in the *Messages* buffer in emacs.

No problem of this sort when I use Carbon Emacs instead.
