Subject: [PATCH] quote: use isalnum() to check for alphanumeric characters
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

isalnum(c) is equivalent to isalpha(c) || isdigit(c), so use the
former instead.  The result is shorter, simpler and slightly more
efficient.
