System: NetBSD topaz.nemeton.com.au 1.3_ALPHA NetBSD 1.3_ALPHA (TOPAZ-DISKLESS) #0: Sat Nov 22 15:15:58 EST 1997 giles@topaz.nemeton.com.au:/usr/src/sys/arch/i386/compile/TOPAZ-DISKLESS i386


>Description:

Note here how the '$' are not lining up with the LHS of the file data
on blank lines:

% cat -be /etc/motd
     1	NetBSD 1.3_ALPHA (TOPAZ-DISKLESS) #0: Sat Nov 22 15:15:58 EST 1997$
$
     2	Welcome to NetBSD!$
$

I'd rather see:

% ./cat -be /etc/motd
     1	NetBSD 1.3_ALPHA (TOPAZ-DISKLESS) #0: Sat Nov 22 15:15:58 EST 1997$
      	$
     3	Welcome to NetBSD!$
      	$

For comparison, -ne gets it "right":

% cat -ne /etc/motd
     1	NetBSD 1.3_ALPHA (TOPAZ-DISKLESS) #0: Sat Nov 22 15:15:58 EST 1997$
     2	$
     3	Welcome to NetBSD!$
     4	$

>How-To-Repeat:
	$ cat -be /etc/motd
