Wrong escape in HTML comments #87

Hi,

when i have "-" in url (eg. http://localhost/repo-branch/), then latte generate wrong urls in HTML comment. This is important, because comments are used for including JS for IE etc. It add space after each "-". I think, that correct behavior is add space only to "-->" sequence. Because now this latte code produce wrong output.

<!--[if lt IE 9]>
    <script src="{$baseUri}/vendor/html5shiv/dist/html5shiv-printshiv.js"></script>
<![endif]-->


<!--[if lt IE 9]>
    <script src="http://localhost/fdv- master/vendor/html5shiv/dist/html5shiv-printshiv.js"></script>
<![endif]-->

Workaround is |noescape, but it is potential security hole.
