These are the variables that control a number of pine functions.  They
come out of the .pinerc and the /usr/local/lib/pine.conf files.  Some can
be set by the user while in Pine.  Eventually all the local ones should
be so and maybe the global ones too.

Each variable can have a command-line, user, global, and current value.
All of these values are malloc'd.  The user value is the one read out of
the user's .pinerc, the global value is the one from the system pine
configuration file.  There are often defaults for the global values, set
at the start of init_vars().  Perhaps someday there will be group values.
The current value is the one that is actually in use.

        Fetch the hostname of the current system and put it in pine struct

   Args: ps -- The pine structure to put the hostname, etc in

  Result: hostname, localdomain, userdomain and maildomain are set


** Pine uses the following set of names:
  hostname -    The fully-qualified hostname.  Obtained with
		gethostbyname() which reads /etc/hosts or does a DNS
		lookup.  This may be blank.
  localdomain - The domain name without the host.  Obtained from the
		above hostname if it has a "." in it.  Removes first
		segment.  If hostname has no "." in it then the hostname
		is used.  This may be blank.
  userdomain -  Explicitly configured domainname.  This is read out of the
		global pine.conf or user's .pinerc.  The user's entry in the
		.pinerc overrides.

** Pine has the following uses for such names:

  1. On outgoing messages in the From: line
	Uses userdomain if there is one.  If not uses, uses
	hostname unless Pine has been configured to use localdomain.

  2. When expanding/fully-qualifying unqualified addresses during
     composition
	(same as 1)

  3. When expanding/fully-qualifying unqualified addresses during
     composition when a local entry in the password file exists for
     name.
        If no userdomain is given, then this lookup is always done
	and the hostname is used unless Pine's been configured to 
	use the localdomain.  If userdomain is defined, it is used,
	but no local lookup is done.  We can't assume users on the
	local host are valid in the given domain (and, for simplicity,
	have chosen to ignore the cases userdomain matches localdomain
	or localhost).  Setting user-lookup-even-if-domain-mismatch
	feature will tell pine to override this behavior and perform
	the local lookup anyway.  The problem of a global "even-if"
	set and a .pinerc-defined user-domain of something odd causing
	the local lookup, but this will only effect the personal name, 
	and is not judged to be a significant problem.

  4. In determining if an address is that of the current pine user for
     formatting index and filtering addresses when replying
	If a userdomain is specified the address must match the
	userdomain exactly.  If a userdomain is not specified or the
	userdomain is the same as the hostname or domainname, then
	an address will be considered the users if it matches either
	the domainname or the hostname.  Of course, the userid must
	match too. 

  5. In Message ID's
	The fully-qualified hostname is always users here.


** Setting the domain names
  To set the domain name for all Pine users on the system to be
different from what Pine figures out from DNS, set the domain name in
the "user-domain" variable in pine.conf.  To set the domain name for an
individual user, set the "user-domain" variable in his .pinerc.
The .pinerc setting overrides any other setting.
