[hackers] [dwm][PATCH] STatuscolor - Add color in the dwm status bar for dwm 6.2.

From: albanb <binmail_AT_free.fr>
Date: Wed, 1 Jul 2020 20:53:57 +0200

From: Alban Brillat <binmail_AT_free.fr>

Statuscolor patch fix for 6.2 release (quite late...). The current patch is really slow,
because of the time spent by the macro TEXTW for the raw characters used
to define color.
Never tried to submit a patch, so don't hesitate if it is not consistent
with the usual best practices.
