Inspect.Algebra.pretty and .line

[tallakt]

It seems that when implementing a multi-line inspect, if you use the line() function the column width counter is not reset for each line. The result being that the second line is broken too early.

Better explained with some code:

defmodule X do                                      
  import Inspect.Algebra                              

  def possible_bug do                                            
    IO.puts(pretty(line(glue("aaaaa", "bbbbb"), glue("ccccc", "ddddd")), 20))
  end
end

iex(114)> X.possible_bug                                                               
aaaaa bbbbb
ccccc
ddddd
:ok

I would have expected the output to be broken into two lines in this instance. It seems that the break between ccccc and ddddd occurs as they all won't fit in 20 characters.
