Add whitespace between hoisted and export in es6 (#30)
Add whitespace between hoisted and export in es6 (#30)

`hoisted` variables had no whitespace separating them from `export` in `es6` mode, causing variables to be interpolated with `export` (ie: `var __targetexport function`).

This PR adds two newlines between hoisted variables and `export` for es6 mode, matching the spacing used in other modes.
