Allow multiple raw blocks #2
Description
The content argument for #sourcecode is searched for the first raw element and everything else is ignored.
The function could take all raw elements and render them together in the following manner:
- If no lang override is given, each raw element used its own lang attribute,
- all code blocks are put in the same frame,
- line numbering is continuous through all code blocks.
As an addition, maybe even other content could stay intact, to add comments between code blocks.
