Behavior of smarttext does not match documentation

The behavior of the type="smarttext" field does not match the documentation. Instead of turning -- into an en-dash and --- into an em-dash as described in the documentation, it turns -- into an em-dash and there is no way to create an en-dash.

This seems to be due to a wrong configuration of the SmartyPants class. The observed behavior corresponds to the default settings of the SmartyPants class while the documented behavior corresponds to the option SMARTYPANTS_ATTR_LONG_EM_DASH_SHORT_EN. The following change fixes the problem:

-            $SmartyPants = new \Michelf\SmartyPants;
+            $SmartyPants = new \Michelf\SmartyPants(\Michelf\SMARTYPANTS_ATTR_LONG_EM_DASH_SHORT_EN);

             $value = $SmartyPants->transform($value);
             if (PERCH_HTML_ENTITIES==false) {

Maybe you could include this change in the next update?

P.S.: Is there no way to subscribe to a new thread by email right when I create it?
