bug#4070: 23.1; ns: cut buffers don't work with --daemon

[Dan Ports]

So it has been a while since I replied to this one. I have been pretty
busy lately and fixing it has not been a high priority since an obvious
workaround now exists: don't start Emacs in screen. :-)

But here is what I found since I more or less gave up on it:

The problem seems to be that [NSPasteboard generalPasteboard] returns
nil. I wasn't able to come up with any reason this should ever happen.
I did find the following thread relating to a similar problem with
MacVim, but it doesn't look like thy found a solution either:

I also noticed that this has also been reported as a bug in MacPorts
four years ago, so I'll post a link to this ticket over there.
