-<!--
-  Nokogiri's pretty-printer is a bit weird.  Regardless of the indentation
-  setting, if an element has no child text nodes then it will be pretty-
-  printed.  This works by adding arbitrary whitespace to that element, and
-  then all of its children are eligible to be pretty-printed.
-
-  If an element has any text nodes at all, then it is not pretty-printed and
-  neither are any of its descendents.
-
-  Adding arbitrary whitespace to <pre> is bad, so we inject zero-width non-
-  breaking spaces to prevent this.  This will render fine but the spaces
-  should be removed before final output to avoid problems with copy+paste.
