  Log:
    Clarify spawn pgroup documentation [ci skip]
    
    * process.c (rb_f_spawn): Be more specific regarding "other
      values" by having "non-zero positive integers" Add nil, the
      default value, as a possible value and what it means.
      Try to use more consistent language.
      [Fix GH-1008]
