[text] Longest common subsequence wrong result?

[Sébastien Piller]

Hi all,
If I call
new LongestCommonSubsequence ().apply ("xxx","yyy")
I get 0 (correct)
If I call 
new LongestCommonSubsequence ().apply ("Gandalf","Sauron")
I get 2 which looks incorrect to me (should have got 1 since there is no 
sequence of 2 chars on both strings. Is it a bug or an expected behavior?
Thanks
