  * "git cherry-pick" and "git revert" can be told to use custom merge

- * "rev-list --objects $revs -- $pathspec" would limit the objects listed
+ * "git cherry-pick" remembers which commit failed to apply when it is
+   stopped by conflicts, making it unnecessary to use "commit -c $commit"
+   to conclude it.
+
+ * "git grep --no-index" did not honor pathspecs correctly, returning
+   paths outside the specified area.

+ * "git rev-list --objects $revs -- $pathspec" would limit the objects listed
    in its output properly with the pathspec, in preparation for narrow

+ * "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.
+
  * "git merge" triggers prepare-commit-msg hook.  Earlier, only "git
    commit" to conclude an interrupted merge triggered the hook, leading to
    an inconsistent overall user experience (js/maint-merge-use-prepare-commit-msg-hook).
 
+ * "git submodule update" used to honor --merge/--rebase option (or
+   corresponding configuration variables) even for a newly cloned
+   subprojects, which made no sense (so/submodule-no-update-first-time).
