Subject: [PATCH v2 1/7] Documentation: fix warning in cat-texi.perl
Message-ID: <20170122024156.284180-2-sandals@crustytoothpaste.net>
In-Reply-To: <20170122024156.284180-1-sandals@crustytoothpaste.net>

Newer versions of Perl produce the warning "Unescaped left brace in
regex is deprecated, passed through in regex" when an unescaped left
brace occurs in a regex.  Escape the brace to avoid this warning.
