Computes the shortest edit script between two sequences (atomic vectors, raw vectors or the lines of two strings) and returns it as data, with Myers algorithm (E. W. Myers (1986) <doi:10.1007/BF01840446>) or patience diff. Builds hunks with context, writes and parses unified diffs, and applies an edit script or a unified diff.
