I realized that before I upgraded to 1.1.5, my workaround to using a ternary operator in interpolated expressions was to use && and || (like someCondition && TruthyResult || FalseyResult) to effectively get the same result. Here's how you'd apply it to your code:

template='{{Line1}}, {{Line2 && (Line2 + \', \') || \'\'}}{{City}}{{State}}{{Zip}}';

The only problem with this setup is if the the TruthyResult doesn't actually return something truthy, the FalseyResult will be returned (just the nature of using && and || like this, compared to the ternary operator). In your code though, (Line2 + \', \') will never be falsey because of the \', \', so it won't be a problem here. But in a more general case, it could be.
