Description
Consider this:
---
format: html
title: "Hello"
---
```{r}
#| eval: true
#| warning = false
cat("hello, world")
```
The error message we get is exceedingly unhelpful:
$ quarto render bad-yaml.qmd
ERROR: YAMLException: can not read a block mapping entry; a multiline key may not be an implicit key (bad-yaml.qmd, 8:19)
7: #| eval: true
8: #| warning = false
~
9: cat("hello, world")
