Yes and no. This is not a safe way to do it because tabs may be
intended to be 8 spaces wide, and that is precisely why it is so
dangerous to mix spaces and tabs... I think Python is too liberal when
allowing that. But
  sed -i 's/\t/    /g' *.py
  bzr diff
allows you to see the extent of the problem. Then I fixed it manually,
just a few lines.
