      r"""Assemble a single line from multiple continued line pieces
  
      Continued lines are lines ending in ``\``, and the line following the last
      ``\`` in the block.
  
      For example, this code continues over multiple lines::
  
          if (assign_ix is not None) \
               and (len(line) >= assign_ix + 2) \
               and (line[assign_ix+1].string == '%') \
               and (line[assign_ix+2].type == tokenize.NAME):
  
      This statement contains four continued line pieces.
      Assembling these pieces into a single line would give::
  
          if (assign_ix is not None) and (len(line) >= assign_ix + 2) and (line[...
  
      This uses 0-indexed line numbers. *start* is (lineno, colno).
  
      Used to allow ``%magic`` and ``!system`` commands to be continued over
      multiple lines.
