I think I'm leaning towards just ditching the helper. The resulting
change looks pretty good:

 	} else

And we just end up sharing the same name buffer (and the "keep" code
path can use the same one, too).

I'll wait until tomorrow to collect any more comments and then send out
a re-roll.

Thanks for reading so carefully.
