  generate issue(s) from wiki(s). Examples:\n\n<pre>{{wiki_to_issue(wiki_page_name)}}\n   </pre>
        this will create a issue: subject=wiki_page_name.title, description=wiki_page_name.content, project=wiki_page_name.project, author=current_user.
      what's more, if wiki_page_name.content include <pre> child_issue:[[wiki_page_name2]] </pre>, another child issue will be created.
      this child process could be a recursion. but the recursion depth is limited to 10.
