Yes, perfekt, that's what i was looking for (and implemented :) )

the trivial solution is of course:
----------------------------------------------------------
s1 = ['this', 'is', 'a', 'test'].join("\n")
s2 = ['this', 'is', 'the', 'test'].join("\n")

(0...s1.size).inject(1) do |l, i|
   puts "difference on line: #{l}" or break if s1[i] != s2[i]
   l = (s1[i] == 10) ? l+1 : l
end
----------------------------------------------------------

buts that no fun..
