Its not really need for now, but as we try to make "nobh"
as default option, it would be nice to have a "-obh" fallback
option - if things go wrong.
Thanks,
Badari
This patch adds "-o bh" option to force use of buffer_heads.
This option is needed when we make "nobh" as default -
and if we run into problems.
