Hello, I ran a simple HTML hello world using vibe.d configured to use 0.7.30 and diet-ng 1.1 in the way indicated in the diet-ng article mentioned in http://vibed.org/blog/posts/introducing-diet-ng .

When I viewed source in Firefox/Linux all of the HTML was on one line, unlike the example here. My template was very simple.

doctype html
html

head
    title Greetings from vibe.d
body
    Hello World

But view source in Firefox showed all html generated from this on one line, not laid out neatly with indentation for the tags as in the link above. How can I get that indentation?
