+Subject: [PATCH] [dwm][statuscmd] better click regions
+
+The main improvement of this patch over the previous version 20210405 is that
+the click region now ends on a matching signal raw byte.
+
+The matching byte is optional, and without it dwm will behave as before.
+
+To take advantage of this feature, scripts need to be modified to print the raw
+byte at the end as well.
+
+In addition, this patch cleanly applies onto master branch.
