>Originator:     Yves-Emmanuel JUTARD
>Release:        3.0.0
>Organization:
THALES Communication
>Environment:
custom environment : recompiled from /src, only some parts of NetBSD are used (TCP/IP stack and some parts of the kernel)
>Description:
type 'route -n show'
In the last column, 'flags' are displayed as letters being put one after another :
route -n show
Routing tables

Internet:
Destination       Gateway            Flags
0.0.0.0/8         default            U
127.0.0.0/-7      127.0.0.1          UGR
127.0.0.1         127.0.0.1          UH
192.0.0.0/8       link#2             U
192.40.34.33      link#2             UH
192.40.34.110     00:60:08:72:xx:xx  UH

This make difficult to compare flags between lines, as stated in "TCP/IP Illustrated, volume 2", chapter 18.2

With a slight modification, one can have this :
route -n show
Routing tables

Internet:
Destination       Gateway            Flags
0.0.0.0/8         default            U
127.0.0.0/-7      127.0.0.1          UG R
127.0.0.1         127.0.0.1          U H
192.0.0.0/8       link#2             U
192.40.34.33      link#2             U H
192.40.34.110     00:60:08:72:xx:xx  U H

Here, when a flag is missing, a blank is inserted instead. It's then easier to spot which flags are set and which one are'nt. It's also easier to compare lines.
>How-To-Repeat:
type 'route -n show' on a machine with internet interfaces.
'netstat' utility may also be affected.

>Fix:
in sbin/route/show.c, after line 324
			*flags++ = p->b_val;
insert those two lines
		else
			*flags++ = ' ';
