Brian Palmer bd9a84a0b7 properly handle amperstands when HTML escaping
escapeExpression, when given a string like ">", was simply returning
">", not escaping the amperstand. This is incorrect, and makes it
impossible to have Handlebars properly escape a
string like "Escaped, <b> looks like: &lt;b&gt;"

If the intention of the user is to not escape these characters, then
{{{}}} or {{&}} should be used
