inconsistency in default content for plus cards+discussion

weird.  don't see why that's not working.

ok, figured it out. *content had "_self+caption" instead of just "+caption".

fixed that instance. not really excited about making it work for _self. I really think of it as _caption being a pretty literal substitute for +caption (which is what it is in the code). If we were going to go much more general than that, we might have to think about some sort of url-friendly set shorthand...

Thanks for figuring that out so quickly.
