Expected compiled blank lines for variables

I'm trying to add the sass-spec suite to node-sass (sass/node-sass#222) but I've run into line ending differences.

Although I've excluded the the 'todo' and 'extend' tests, I'm seeing failures between the number and placement of line endings https://travis-ci.org/andrew/node-sass/builds/16845180. Is this a node-sass difference or is the ruby runner just more tolerant to these difference?

Any interest in upstreaming this to the libsass CI test suite if this is resolved?

Yeah, little discrepancies like this have been an issue for us (not just whitespace, but also things like color formats, rounding differences, etc). @hcatlin told me that there's a way to get Ruby Sass to output the abstract syntax tree (or something along those lines), so maybe that'll give us a way to normalize the output before diffing.
