From e3c7e92f1090204ba945c063b7aba3b3b1d8095b Mon Sep 17 00:00:00 2001
From: Aaron Griffin <aaron@archlinux.org>
Date: Sun, 4 Feb 2007 01:36:45 +0000
Subject: * unified the progress bars (fill_progress function) * fixed progress
 output (needs an fflush to move cursor properly) * broke display_targets
 function out, to display a list of syncpkgs in   preparation for a -Qu option
 * added get_update_time function to deal with progress functions that
 shouldn't   update too fast due to output redraw speeds
