Guido> And yes, it's a wart, but I don't know how to fix it.

I did a little digging and noticed this comment dating from v 2.5 (Jul 91): /* Lines with only whitespace and/or comments shouldn't affect the indentation and are not passed to the parser as NEWLINE tokens, except totally empty lines in interactive mode, which signal the end of a command group. */ Not surprisingly, given the age of the change, your fingerprints are all over it. ;-) I suspect if the code beneath that comment was executed only when the indentation level is zero we'd be okay, but I don't know if the tokenizer has that sort of information available. I'll do a little more poking around.

Please do. The indentation level should be easily available, since it is computed by the tokenizer.
