Subject: the notation of AF_LOCAL sockets in list-process
Date: Mon, 24 May 2010 15:45:36 +0900 (JST)

This is a bug report with a patch. Please include the patch
if appreciated.

When `local' is given as :family keyword arugment of `make-network-process',
AF_LOCAL(also known as AF_UNIX) socket is created. This behavior is not changed
even if :host keyword arugment is given. This is O.K. But `list-process' doesn't 
work as we expected.

I'll explain the detail with example:

    (let ((port "/dev/log"))
      (make-network-process :name "syslog"
			    :host "127.0.0.1"
			    :noquery t
			    :service port
			    :family 'local
			    :type 'datagram))

Although "127.0.0.1" is specified at :host but `local' is
specified at :family, so `make-network-process' creates AF_LOCAL socket.
But M-x list-process tells

    Proc	  Status   Buffer Command
    ----	  ------   ------ -------
    syslog        open	   (none) (network datagram connection to 127.0.0.1)

This should be 


    Proc	  Status   Buffer Command
    ----	  ------   ------ -------
    syslog        open	   (none) (network datagram connection to /dev/log)

	* process.c (Fmake_network_process): Reset `host'
	property if family is AF_LOCAL.
