Still comes to the same thing. The only diff is that tabs get treated as eight spaces instead of one (and the bug that a tab elsewhere in the line will result in indentation, which is fixed by lstripping the tab-expanded form). It won't perfectly round-trip with a mixture of tabs and spaces; as it is, you can pick one or the other and run with it. Anyway, the main point is that indentation will work. Sure you might have ugly narrow code, but it'll run with one-space indents. ChrisA -- http://mail.python.org/mailman/listinfo/python-list
