That's a really unfortunate result of word wrapping the doc string from
team.yaml

I wonder if it's possible to recognise literal doc strings, with
embedded newlines and emit them line by line. That would require adding
the | symbol to the doc string in team.yaml, like this:

    doc: |
      The team nested layout of get/set msg looks like
          [TEAM_ATTR_LIST_OPTION]
              [TEAM_ATTR_ITEM_OPTION]
                  [TEAM_ATTR_OPTION_*], ...
              [TEAM_ATTR_ITEM_OPTION]
                  [TEAM_ATTR_OPTION_*], ...
              ...
          [TEAM_ATTR_LIST_PORT]
              [TEAM_ATTR_ITEM_PORT]
                  [TEAM_ATTR_PORT_*], ...
              [TEAM_ATTR_ITEM_PORT]
                  [TEAM_ATTR_PORT_*], ...
              ...

Sure, you might occasionally get some messy line wrapping but I think
that's better than flowing literal blocks of text.
