When parsing inner contexts (@include, @media, etc) when a prefix was present it would include the prefix on the new chain, whereas it should only be included on the split chain. This was only visible with multiple nests inside a new parser context, since at the top level context there wouldn't be a prefix, and if the @includes only had 1 level declarations the prefix wouldn't be merged back. This fixes it.
Also corrected the col increase for the @fn:: match, and added a no_count marker for the expansion of an @expandable
