You forgot to provide the pointers to the documentation that I
requested, explaining why you would expect this. The documentation for
`server-auth-dir' says "We only use this if `server-use-tcp' is non-nil.
Otherwise we use `server-socket-dir'."
You didn't set `server-use-tcp' in your instructions above. If I insert
(setq server-use-tcp t)
before
(server-start)
in your step (2), evaluating (server-start) gives me the error message
"The directory `~' is unsafe". So it looks like emacsclient is working
as expected.
Is there a reason you want emacsclient to use TCP instead of (the
default) local sockets? I suspect this is due to your previous use of
native Windows emacs. Here's a quote from the emacsclient info file:
An Emacs server usually uses an operating system feature called a
"local socket" to listen for connections. Some operating systems,
such as Microsoft Windows, do not support local sockets; in that
case, Emacs uses TCP instead.
BTW, I'm working in a test build of emacs-24.1. I haven't checked to
see what happens in emacs-23.4, but it doesn't seem relevant at this point.
