Commit Message

diff: simplify LCS_matrix()

* Initialise $x[$i] to new listref [0] in one statement, instead of assigning list element 0 separately
* Calling standard max() function avoids temporary variables when compared items are different
* Write loops in idiomatic form with ranges
* This was intended as a readability change, but I observed that when generating diffs on a large text files the performance is slightly improved
