      Return a string that is whitespace except at p[i] which is replaced with char.
      If i is None then all the indices of the string in p are replaced with char.
  
      Example:
  
          >>> ss = ["a.string[0].with_separators"]
          >>> chars = list(".[]_")
          >>> ss_split = split_multichar(ss, chars)

          ['a', 'string', '0', '', 'with', 'separators']
          >>> ss_pos = split_string_positions(ss_split)
          >>> ss[0]
          'a.string[0].with_separators'
          >>> display_string_positions(ss_pos,4)
          '            ^'
          >>> display_string_positions(ss_pos,4,offset=1,length=3,char="~",trim=False)
          '             ~~~      '
          >>> display_string_positions(ss_pos)
          '^ ^      ^ ^^    ^'
      :param (list) p: A list of integers.
      :param (integer|None) i: Optional index of p to display.
      :param (integer) offset: Allows adding a number of spaces to the replacement.
      :param (integer) length: Allows adding a replacement that is the char
                               repeated length times.
      :param (str) char: allows customizing the replacement character.
      :param (boolean) trim: trims the remaining whitespace if True.
