+ 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.
