Thanks for this -- very handy! I found that the function_exists('show_tweets') check always fails so I've simply been using <?php show_tweets(); ?> on its own, just in case anyone else is finding that nothing is showing.
EDIT: Whoops, spoke too soon -- seemed to work on the live site at first, then stopped displaying tweets (ditto in the settings preview), then the page stopped rendering past the widget! Bizarrely perfect from localhost, though. Web dev!
