Quoting yaml.org: “YAML is a human-friendly data serialization language
for all programming languages.”  (See https://yaml.org/spec/1.2.2/ for
all the gory details.)  Both whitespace and line breaks are semantically

One meaningful behavior for `fill-paragraph' could be to allow it only
within YAML flowed blocks and flow scalars (see

    script: |

      apt-get -y update
      apt-get -y install my-necessary-package

      The above script updates the system and installs a necessary

      This is a second line, where we give more information We had to
      leave an empty line in the yaml file to get a line break.
