Nit: I think if you remove the quoted word "template" and the colon after it,
this is clearer.

[please use gerrit instead, 2016/01/14 17:51:57]

Done.

+  // 2. Two or more consecutive dollar signs in the template string will not
+  //    expand correctly.
+  // 3. "${" anywhere in the template string is invalid.
+  // 4. "\n" embedded anywhere in the template string, or an empty template
+  //    string, can be used to separate paragraphs. It is not possible to create
+  //    a completely blank line by using two consecutive newlines (they will be
+  //    treated as a single newline by views::StyledLabel).

Nit: Per the style guide, static methods go below the constructor/destructor.

[please use gerrit instead, 2016/01/14 17:51:57]

Done.
