[multi-tty] emacsclient resets working directory

[csant]

I am not sure this is really a bug (I would consider it such), but it  
certainly is a major annoyance (is it expected behaviour?).  Not sure it  
has been already addressed by David Kastrup when speaking about  
environment.

Start an emacs session
        $ cd ~ && emacs -Q
and `M-x server-start'.  When finding a file from the *scratch* buffer, it  
will start looking from $PWD ( ~/ )

Connect an emacsclient, go back to the main server emacs and find a file  
in *scratch*: it will start looking from the emacsclient's $PWD.  Even  
though I might imagine some use cases, this sounds more like an unexpected  
behaviour: to the user both the server and the client frame are perceived  
as separate emacs instances and the $PWD of the emacsclient should not  
modify the server's one.
