* Fine tune whitespace The EEx outut now emits more human-readable and predictable formatting. This includes proper indenting, at least for each "root" template. * Internal whitespace control You can now use a bang version of any nonvoid tag to emit the markup witout the internal whitespace. This means that there will not be a newline emitted after the opening tag and before the closing tag.
