No support for multiline attributes

[avalanche1]

div(data-html='<p>First very long line</p>' +
        '<p>Second very long line</p>' +
        '<p class="warn">Third very long line</p>')

Produces only <div data-html="<p>First very long line</p>"></div>.

I believe backslash is the way to break up long strings: Multiple Lines for Long Attribute Value in Jade

I think the syntax is official, since I've seen it output from an HTML to Jade converter.

Yes, converter uses backslash. But meteor jade compiler gives
Jade syntax error: Unexpected token

[dalgard]

The backslash must be written inside the string – to escape the newline. The string is ended with a quotation mark only on the final line.

Neither \, nor + work here.
