Subject: [PATCH 2/2] cclass: cleanup
Date: Tue, 19 Sep 2017 04:56:00 +0200 [thread overview]
Message-ID: <20170919025600.11900-3-luc.vanoostenryck@gmail.com> (raw)
In-Reply-To: <20170919025600.11900-1-luc.vanoostenryck@gmail.com>
The table of charatcer classes: cclass[] used to contain information
about escaped chars but this is no more the case.
Simplify the table by merging sequence of character of same classes
and remove old comment about the escape.
