mailto: no correctly rendered

What steps will reproduce the problem?
1. create some markdown with a link to send an email like 
[mail](email@me.com)
2. call the converter on the string
string = '[mail](mailto:email@me.com)'
converter.makeHtml(string);
3.

What is the expected output? What do you see instead?
The output should be 
<a href="mailto:mail@me.com">mail</a>

instead we have
<a href="{absoluteURL}mailto%3Amail@me.com">mail</a>

What version of the product are you using? On what operating system?

Please provide any additional information below.

This has been fixed by tweaking one of the attackLab functions (below), to 
avoid encoding the ":" when preceeded by "mailto".

function encodeProblemUrlChars(url) {
   if (!url)
     return "";
//if we have an "email:" type of link then do not encode the ":"
   else if (/mailto:/.test(url))
     return url;
   else {
     var len = url.length;
     return url.replace(_problemUrlChars, function (match, offset) {
    if (match == "~D") // escape for dollar
          return "%24";
    if (match == ":") { 
      if (offset == len - 1 || /[0-9\/]/.test(url.charAt(offset + 1)))
        return ":"
    } 
    return "%" + match.charCodeAt(0).toString(16);
     });
  }
}
