Subject: server-eval-and-print only returns non-nil values
Date: Sun, 3 Jul 2011 15:38:09 +0200	[thread overview]
Message-ID: <CAAeL0SS70xdZKU68cke8Mr_D5OT6p2v34E2eJXCB9Fw9k3Z-rg@mail.gmail.com> (raw)

Is there any reason why server-eval-and-print only returns non-nil values?

  C:\> emacsclient -e "(file-exists-p \"C:/\")"
  t

  C:> emacsclient -e "(file-exists-p \"Z:/\")"

  C:>


If not, I'd like to fix it with the trivial patch below.

	* server.el (server-eval-and-print): Return any result, even nil.
