Gratuitous string concatenation occurs when escaped curly braces are present

[lazd]

The output is less than ideal when \{ and \} are present -- there is additional string concatenation going on in the compiled function that is pretty ugly:

Template:

\{\{Outer with data\}\} {{data.name}}

<code>
  \{\{Nested\}\}
</code>

<code>
  \{\{Nested with data\}\} {{data.name}}
</code>

Output:

(function anonymous(data_0) {
  var frag = document.createDocumentFragment();
  var data = data_0;
  var el0 = document.createTextNode("{"+"{"+"Outer with data"+"}"+"}"+" "+data_0["name"]+"\n\n");
  frag.appendChild(el0);
  var el1 = document.createElement("code");
  el1.textContent = "\n  "+"{"+"{"+"Nested"+"}"+"}"+"\n";
  frag.appendChild(el1);
  var el2 = document.createTextNode("\n\n");
  frag.appendChild(el2);
  var el3 = document.createElement("code");
  el3.textContent = "\n  "+"{"+"{"+"Nested with data"+"}"+"}"+" "+data_0["name"]+"\n";
  frag.appendChild(el3);
  return frag;
})

The parser could be modified to concatenate the braces into an existing content block instead of creating a new one, or DOMly could be fixed to combine content blocks into a single string instead of concatenating multiple strings.

This is due to the fixes for #7. @cif
