Formatter: do not indent/newline everything

[cdietrich]

hi we like to do sth like the following in the formatter

something {
   somechild mychild
   somechildren a,b,c
}

when indenting between {``}
it gets formatted as

something {
   somechild mychild
   somechildren a
   ,b
   ,c
}

is there a better way to prevent this than sth like

// selective formatBody
    const bracesOpen = formatter.keyword("{")
    const bracesClose = formatter.keyword("}")
    const interiors = CstUtils.getInteriorNodes(bracesOpen.nodes[0], bracesClose.nodes[0])
    for (const i of interiors) {
      if (!i.text.startsWith(",")) {
        console.log("xxxx", i.text)
        formatter.cst([i]).prepend(FormatingOptions.indent)
      }
    }

    bracesClose.prepend(FormatingOptions.lineBreak)

we also do sth like

doubleIndent: {
    options: {},
    moves: [
      {
        tabs: 2,
        lines: 1,
      },
    ],
  },

would that be something worth to contribute? e.g. a new method or add param to Formatting.indent
