From 82b83da8d30fb8d1f04f7dd7ac769ceb6ab431c3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Thu, 29 Sep 2016 20:13:05 +0200 Subject: [PATCH] pretty: avoid adding reset for %C(auto) if output is empty We emit an escape sequence for resetting color and attribute for %C(auto) to make sure automatic coloring is displayed as intended. Stop doing that if the output strbuf is empty, i.e. when %C(auto) appears at the start of the format string, because then there is no need for a reset and we save a few bytes in the output.
