From 9f60645e57dc7d3f64edea001b20514b664c3c30 Mon Sep 17 00:00:00 2001
From: Miles Bader <miles@gnu.org>
Date: Fri, 20 Jun 1997 05:38:01 +0000
Subject: (netfs_get_translator):   Use argz_replace instead of doing it
 ourselves. (create_host_node):   Set the times of the new node. (str_append):
   Function removed.
