Tabnanny is intended to check whether indentation
has mixed tabs and spaces. Files with mixed tabs
and spaces _can_ compile just fine if the editor
that produced them agrees with the compiler about
the number of spaces that a tab occupies.

On the other hand, such files are quite likely to
be messed up almost beyond repair if one tries
to edit them in an editor that treats tabs differently
from the one that produced it.

Files that stick to one or the other can always
be edited and compiled properly. The python
recommendation is to use spaces, but not
everyone agrees with this.

Most modern Python-aware editors handle
the situation reasonably, although you may have
to set parameters.
