Don't fallback to parse usual R comments in Quarto #2225

Open cderv opened 1 year ago

cderv commented 1 year ago

This is related to discussion in https://github.com/quarto-dev/quarto-cli/issues/4306

Making this draft PR to test a scenario and discuss. This is WIP

Regarding second commit, if we don't error but just don't fallback we would get this behavior with an obscure error due to in chunk content not being parsed as option
