strange conditional logic in CSVLint

validate.rb

if type == :stray_quote && !wrapper.line.match(csv.row_sep)
  # above evaluates to true && false
  # however it is false only by placing bang against wrapper.line.match(csv.row_sep) which evals to either
  # nil or MatchData - seems a strange way to order flow
  # basically it want's whatever is matched against the row_sep (generated from the CSV.new of data inputted) to not match
  # because if it matches then bang generates a false and only a stray_quote is logged
 build_errors(:line_breaks, :structure)
 
 # the tests that exist pass \r rather than \r\n when testing for line breaks
