The enclosed patch adds the following switches:
  -ut, --use-tabs
  -nut, --dont-use-tabs

Also, in looking over the code, I notice that tabsize must be an even
power of 2 in order to work properly.  This restriction is not mentioned
in the documentation, and is probably not intended.

Thanks,
Rick
