templatekw: add labelify to _showlist to mimic ''.join()

This patch represents one of the prices of labeling a list of values: because this is now a list of dictionaries, we can't use ''.join(). Therefore, this hacks the yield to append a space.

Mayhaps we could use the built-in template version of 'join'?
