Here is the full output:

jrm@phe ~ % ssh -f gly 'emacsclient -nc'
0;jrm@phe|~emacsclient: can't find socket; have you started the server?
To start the server in Emacs, type "M-x server-start".
jrm@phe ~ % ("emacs")
Loading autorevert...
Loading autorevert...done
Loading paren...
Loading paren...done
Starting Emacs daemon.
Emacs daemon should have started, trying to connect again

Another prompt shows up, but I'm not doing anything after
ssh -f gly 'emacsclient -nc'.

In my ~/.ssh/config for the host gly I have:
ForwardX11 yes
ForwardX11Trusted yes

I'm not manually setting DISPLAY.

I've pasted the environments for each setting below.
