[PATCH 07/17] perf ui: Get rid of callback from __hpp__fmt()

From: Namhyung Kim
Date: Tue Apr 15 2014 - 23:11:30 EST


The callback was used by TUI for determining color of folded sign
using percent of first field/column. But it cannot be used anymore
since it now support dynamic reording of output field.

So move the logic to the hist_browser__show_entry().
