Bug#561161: patch merged upstream

[Martin Pool]

A patch similar to this has been merged to upstream
<http://net-tools.git.sourceforge.net/git/gitweb.cgi?p=net-tools/net-tools;a=commitdiff;h=f1f89328cccf92824ab436fa43068603eb43e34d>.

Since the last upstream release was eleven years ago, I don't think
it's a good idea to wait for the next one. Maybe Debian could
cherrypick this fix or take a snapshot from trunk?
