From dbaee2672be14374acb17266477c19294c6155f3 Mon Sep 17 00:00:00 2001 From: Jeff Smith Date: Sat, 28 Oct 2017 21:43:26 -0500 Subject: ui-blame: Allow syntax highlighting Place file contents into a single block so that syntax highlighting can be applied in the usual fashion. Place the alternating color bars behind the file contents. Force the default syntax highlighting background to transparent.
