  The comment is correct.  splitfields(s) is synonymous with split(s),
and splitfields(s, ' ') is synonymous with split(s, ' ').
  If the second arg is omitted, any stretch of whitespace is used as
the separator, but if ' ' is supplied, exactly one space is used to
split fields.
  split(s, None) is synonymous with split(s), splitfields(s), and
splitfields(s, None).
