v0.4.2 removes necessary whitespace

My HTML pages are breaking because the v0.4.2 release strips the whitespace between these ego tags:

```
<header class="row">
  <div class="col-5">
    <h3><%= t(req, "Batch") %> <%= st.Bid %></h3>
  </div>
</header>
```

The generated `<h3>` should contain `Batch abc123` but contains `Batchabc123`. v0.4.1 works fine.
