diff-lcs 1.2.2

Diff::LCS computes the difference between two Enumerable sequences using the McIlroy-Hunt longest common subsequence (LCS) algorithm. It includes utilities to create a simple HTML diff output format and a standard diff-like tool. This is release 1.2.2, fixing a bug that prevented comparison of values that are not US-ASCII-compatible. Thanks to Jon Rowe for finding and providing most of the work behind this issue. This is a recommended release.
