+From 35418d156fccb922710f6ca80a1f3972ba88b42f Mon Sep 17 00:00:00 2001

+Subject: [PATCH] Add colors to status message in bar.
+
+This patch matches the format used by
+https://dwm.suckless.org/patches/statuscolors/ -- An \x01 character
+switches to the normal foreground/color combo, \x02 switches to the
+color combo used for selected tags, \03 is set by default to black on
+yellow, \04 is white on red.
+
+These color settings are defined in the colors array in config.def.h.
+More can be added, but don't have more than 32, or you'll start hitting
+real ASCII.
+
+This applies cleanly on mainline dwm from commit 022d076 (Sat Jan 7
+17:21:29 2017 +0100) until at least b69c870 (Sat Jun 2 17:15:42 2018
++020).
