Subject: [PATCH] Fix {strip} block removing spaces between HTML attributes.

{strip} removed spaces between HTML attributes in some cases like e.g.,
 `<a href=\"{'genLink'}\"\n target=\"_blank\">`. This is due to the Smarty tag in the middle splitting the text block up and so the regex does not recognize the HTML attribute.
