variable: MAX_MEMBERS_PER_GROUP. Used for the split groups support.

  and parse, or before it is closed.

  close group to split groups if MAX_MEMBERS_PER_GROUP is set.
  This fixes gpasswd and chgpasswd when split groups are used.

   parameters). This matches with the prototype definition.
 * src/groupmems.c: Avoid ++i when i is also used in the same line.
