Update ruby-diff-lcs to 1.2.1.

== 1.2.1 / 2013-02-09

* Bugs Fixed:
  * As seen in rspec/rspec-expectations#200, the
    release of Diff::LCS 1.2 introduced an unnecessary public API change to
    Diff::LCS::Hunk (see the change at
    rspec/rspec-expectations@3d6fc82c for details).
    The new method name (and behaviour) is more correct, but I should not have
    renamed the function or should have at least provided an alias. This
    release restores Diff::LCS::Hunk#unshift as an alias to
    #merge. Note that the old #unshift behaviour was incorrect and will not be
    restored.

== 1.2.0 / 2013-01-21
* Minor Enhancements:
  * Added special case handling for Diff::LCS.patch so that it handles patches
    that are empty or contain no changes.
  * Added two new methods (#patch\_me and #unpatch\_me) to the includable
    module.
* Bugs Fixed:
  * Fixed issue #1 patch direction detection.
    halostatue/diff-lcs#1
  * Resolved issue #2 by handling string[string.size, 1] properly (it returns
    "" not nil). halostatue/diff-lcs#2
  * Michael Granger (ged) fixed an implementation error in Diff::LCS::Change
    and added specs in pull request #8. Thanks!
    halostatue/diff-lcs#8
  * Made the code auto-testable.
  * Vít Ondruch (voxik) provided the latest version of the GPL2 license file in
    pull request #10. Thanks! halostatue/diff-lcs#10
  * Fixed a documentation issue with the includable versions of #patch! and
    #unpatch! where they implied that they would replace the original value.
    Given that Diff::LCS.patch always returns a copy, the documentation was
    incorrect and has been corrected. To provide the behaviour that was
    originally documented, two new methods were added to provide this
    behaviour. Found by scooter-dangle in issue #12. Thanks!
    halostatue/diff-lcs#12
* Code Style Changes:
  * Removed trailing spaces.
  * Calling class methods using '.' instead of '::'.
  * Vít Ondruch (voxik) removed unnecessary shebangs in pull request #9.
    Thanks! halostatue/diff-lcs#9
  * Kenichi Kamiya (kachick) removed some warnings of an unused variable in
    lucky pull request #13. halostatue/diff-lcs#13
    Thanks!
  * Embarked on a major refactoring to make the files a little more manageable
    and understand the code on a deeper level.
  * Adding to http://travis-ci.org.
