centering

I've noticed that occasionally Plucker centers text it shouldn't.  E.g.,
http://www.pbs.org/wgbh/nova/doctors/oath_classical.html
(Which is left justified by IE and lynx).  What's going on?  I don't know
much about the distiller.  I am tempted to make a local mod in the viewer
for myself and my wife that forces left justification when desired, unless
there is some way to fix this in the distiller.
