Escaping bare attributes content

[elia]

Passing signed_in_html as an attribute value directly doesn't properly escape it

    - signed_in_html  = render('application/header_signed_in')
    .account.js-account(data-signed-in-html=signed_in_html)

instead it seems to work when used in an interpolated string:

    - signed_in_html  = render('application/header_signed_in')
    .account.js-account(data-signed-in-html="#{signed_in_html}")

Fixed in v0.8.1
