Subject: t6036: Add a second testcase similar to the first but with content
 changes

c94736a (merge-recursive: don't segfault while handling rename clashes
2009-07-30) added t6036 with a testcase that involved dual renames and a
criss-cross merge.  Add a test that is nearly identical, but which also
involves content modification -- a case git currently does not merge
correctly.
