--no-debug option seems to only remove first line of debug info

[derickvn]

Here is an example of a simple template with and without debug:
Template:

html
    head
        title Skeleton template
        meta(charset="UTF-8")
        meta(name="viewport" content="width=device-width, initial-scale=1.0")
        link(rel="stylesheet" type="text/css" href="/css/styles.css")
    body
        #content.container-fluid Loading Application...
        script(src="/lib/jquery/jquery-2.2.3.min.js")
        script(src="/lib/bootstrap/js/bootstrap.min.js")
        script(src="/js/scripts.js")

without --no-debug:
