Multipass templating and conditionals

[kaufers]

Doing an if check on a variable that is not defined always equates to true when multipass is enabled. For example:

{{ if (var "/some/var") }}

If multipass is enabled then this resolves to:

{{ if "{{ var `/some/var` }}" }}

Since the value in the conditional is a non-empty string then the if check always evaluates to true.
