Format the specified `mask` to the specified output `stream` at the optionally specified indentation `level` and return a reference to the modifiable `stream`. If `level` is specified, optionally specify `spacesPerLevel`, the number of spaces per indentation level for this and all of its nested objects. Each line is indented by the absolute value of `level * spacesPerLevel`. If `level` is negative, suppress indentation of the first line. If `spacesPerLevel` is negative, suppress line breaks and format the entire output on one line. If `stream` is initially invalid, this operation has no effect.
