simply ahead of H. The index and the work tree contains a state that
is derived from H, but may also have local changes. This test checks
all the combinations described in the two-tree merge "carry forward"
-rules, found in <Documentation/git-read-tree.txt>.
+rules, found in <Documentation/git read-tree.txt>.
In the test, these paths are used:
bozbar - in H, stays in M, modified from bozbar to gnusto
