test_description='Two way merge with read-tree -m $H $M
-This test tries two-way merge (aka fast forward with carry forward).
+This test tries two-way merge (aka fast-forward with carry forward).
There is the head (called H) and another commit (called M), which is
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
