[PATCHv2 15/56] t6022: Add testcase for merging a renamed file with a simple change

[Elijah Newren <newren@gmail.com>]

This is a testcase that was broken by b2c8c0a (merge-recursive: When we
detect we can skip an update, actually skip it 2011-02-28) and fixed by
6db4105 (Revert "Merge branch 'en/merge-recursive'" 2011-05-19).  Include
this testcase to ensure we don't regress it again.

Changes since v1: Check that the result of the merge is actually
  correct; had I done that in v1, I would have caught the bug that
  Junio found the hard way.
