Subject: [PATCH v2 06/13] show: Feed the sprinter down to part formatters
Date: Sat, 28 Jul 2012 00:29:07 -0400

There are several levels of function calls between where we create the
sprinter and the call to the part formatter in show_message. This
feeds the sprinter through all of them and into the part formatters.
