Excess White Space
Template whitespace may be omitted from either side of any mustache statement by adding a `~` character by the braces. When applied all whitespace on that side will be removed up to the first handlebars expression or non-whitespace character on that side.
{{#each nav ~}}<a href="{{url}}">{{~#if test}} {{~title}} {{~^~}} Empty {{~/if~}} </a>{{~/each}}
will result in this `<a href="foo">bar</a><a href="bar">Empty</a>` ddd
Note: Can only be used in HTML Templates
