+BEHAVIORAL DIFFERENCES
+-----------------------
+
+ * empty commits:
+
+ am-based rebase will drop any "empty" commits, whether the
+ commit started empty (had no changes relative to its parent to
+ start with) or ended empty (all changes were already applied
+ upstream in other commits).
+
+ merge-based rebase does the same.
+
+ interactive-based rebase will by default drop commits that
+ started empty and halt if it hits a commit that ended up empty.
+ The `--keep-empty` option exists for interactive rebases to allow
+ it to keep commits that started empty.
+
+ * empty commit messages:
+
+ am-based rebase will silently apply commits with empty commit
+ messages.
+
+ merge-based and interactive-based rebases will by default halt
+ on any such commits. The `--allow-empty-message` option exists to
+ allow interactive-based rebases to apply such commits without
+ halting.
+
+ * directory rename detection:
+
+ merge-based and interactive-based rebases work fine with
+ directory rename detection. am-based rebases sometimes do not.
