+Subject: [PATCH] Tools that take --dec=X option should only accept digits
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Right now the argument of --dec is passed to atoi(3) which returns 0
+on conversion error.  Therefore, --dec=A was not rejected and was
+equivalent to --dec=0 by mistake.
