    *   Fixed an error for bin/ldiff --version. Fixes [issue #21][].
    *   Force Diff::LCS::Change and Diff::LCS::ContextChange to only perform

    *   Fix tab expansion in htmldiff, provided by Mark Friedgan in
        [pull request #25][].
    *   Silence Ruby 2.4 Fixnum deprecation warnings. Fixxues [issue #38][] and
