From 4a3e9f26cb57ab4a62cf929c551dc21c8b8e993c Mon Sep 17 00:00:00 2001
From: des <des@FreeBSD.org>

Subject: Add -N option to specify a netrc file. Fix handling of -v option.
 Don't treat negative offsets as valid positive ones. Clean up the ETA and
 transfer rate code.  Show transfer rate along with ETA if the verbose level
 is higher than 1.
