I thought Jim presented a good case for an exception for the trailing
delimiter, but otherwise disallowing single-line 'fat' strings (single-line
multi-line strings?) seems to mostly have upside.

This seems OK to me too, but is there good return on complexity? Closing
delimiter influence can also be used to opt out of stripping. Are there
enough use-cases to justify a second opt-out mechanism? And does it have to
be decided now, or could it be added later?
