Newlines in template parameters?

[theangrydev]

I was hoping to be able to do something like this for arguments that have multiline content:

{{ helper 'line1
line2
line3' }}

But I get an error like this:

com.github.jknack.handlebars.HandlebarsException: inline@69d4e0a5:1:14: found: ''line1', expected: '}}'

Is there a recommended way to handle multiline arguments? Happy to submit a PR if someone can guide me to the right place to modify to support this
