w output all screwed up

[Navindra Umanee <navindra@cs.mcgill.ca>]

Hi, this is on slink:

(M-x auto-fill-mode)

aseq:/usr/local# w
  1:13am  up 3 days, 22:27,  4 users,  load average: 1.00, 1.00, 1.00
USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU  WHAT
xxxxxxxx ttyp0    dak.xxxxxxxx.ca  11:15pm 13:45   0.33s  0.24s             tcsh
xxxxxxxx ttyp1    palpatine.xxxxxx  6:58pm  2:09m  0.55s  0.52s             tcsh
xxxxxxxx ttyp2    obiwan.xxxxxxxx.  3:00pm  1:33m 11:15    ?     -
xxxxxxxx ttyp3    tk421.xxxxxxxx.c 11:27pm  0.00s  0.30s  0.03s  w 

Why does the output screw up like this?  In particular, why are the
tcsh's so out of wack?  This is the same on the less cluttered "w -s".

Please [g]cc: me.

Thanks,
Navin.

PS Why was the default output of w changed?  Wasn't "w -s" the default
   output before?
