+ * "git clone /no/such/path" did not fail correctly (jk/fail-null/clone).

+ * "git checkout $other_branch" silently removed untracked symbolic links
+ in the working tree that are in the way in order to check out paths
+ under it from the named branch (js/checkout-untracked-symlink).

+ * "git diff --stat -B" ran on binary files counted the changes in lines,
+ which was nonsensical (jk/diffstat-binary).
+
+ * "git diff -M" opportunisticly detected copies, which was not
+ necessarily a good thing, especially when it is internally run by
+ recursive merge.
