Strange `@partial` whitespace

[erburns-fcn]

In the example, there is this snippet:

<!-- Partials -->
@partial example_partial

<!-- Partials with positional args -->
@partial mailto(.user.email, "Welcome to Jetzig!")

Which is rendered as:

<!-- Partials --><span>An example partial</span>

<!-- Partials with positional args --><a href="mailto:user@example.com?subject=Welcome to Jetzig!">user@example.com</a>

I find this whitespace confusing. Shouldn't it be something like this?:

<!-- Partials -->
<span>An example partial</span>

<!-- Partials with positional args -->
<a href="mailto:user@example.com?subject=Welcome to Jetzig!">user@example.com</a>

It looks like that is what it used to be until the test was changed in 7ff4f58 with no explanation. What is the reasoning behind this?

In the middle of overhauling this for 0.15/0.16 right now so I will look out for it. I suspect it has to do with zmd.
