    No, the dumb thing was shipping a Python implementation which accepted both
tabs and spaces for indentation in the same file.  Tabs vs. spaces is
a religious issue, but mixing the two is unquestionably bad.

    Python 3.x, finally, detects inconsistent tab/space indentation. But that
should have been in Python 0.001, so that no inconsistent code ever escaped
into the wild.

    Check to see if your code will go through Python 3.x without indentation
complaints.  If it won't, you need to fix it before re-indenting.
