It isn't just #hash, but also things like #dict, #int, #len at the
start of a comment line which defeats IDLE's colorization algorithm.
Interestingly, things like #while or #for behave as expected so it
seems to be built-ins rather than keywords which are the problem. To
answer my own question - this is pretty clearly a (harmless) bug.
