I don't think we want to duplicate all of these tests.  Perhaps we could
add a small number of additional tests in an existing signing test that
makes sure both the new and the old configuration work as expected, and
assume that the entire codebase will honor those config settings.

Thx for your feedback. I will update the necessary existing tests and re-submit the patches.

+ | \
+ |   J - K - L - M            (no-conflict-branch)
+  \
+    N - O - P                 (no-ff-branch)
+
+ where A, B, D and G all touch file1, and one, two, three, four all
+ touch file "conflict".
