Context

This bug is due to the number of backslashes in the message content; as a result, the block has not colored the exact block size for the first and the last line. The solution is to remove these antislashes.

lines.each do |line|
  messages << %(#{line}#{" " * (len - line.gsub('\\', nil).size)})
end

Thanks to #gsub method, the block is formated correctly.
