Multiple spaces between selector classes

[tschwartz]

Currently it seems like there is an issue where multiple spaces between classes will cause that selector to not be applied.

.parent .child-0 {}
.parent  .child-1 {} // double space between classes in selector will not be applied to element

Once fixed of course things are fine but was quite painful to track down.
