 # Notes: In commit A, directory z got renamed to y.  In commit B, directory z
 #        did NOT get renamed; the directory is still present; instead it is
 #        considered to have just renamed a subset of paths in directory z
-#        elsewhere.  Therefore, the directory rename done in commit A to z/
-#        applies to z/d and maps it to y/d.
+#        elsewhere.  However, this is much like testcase 6b (where commit B
+#        moves all the original paths out of z/ but opted to keep d
+#        within z/).  This makes it hard to judge where d should end up.
 #
 #        It's possible that users would get confused about this, but what
-#        should we do instead?  Silently leaving at z/d seems just as bad or
-#        maybe even worse.  Perhaps we could print a big warning about z/d
-#        and how we're moving to y/d in this case, but when I started thinking
-#        about the ramifications of doing that, I didn't know how to rule out
-#        that opening other weird edge and corner cases so I just punted.
+#        should we do instead?  It's not at all clear to me whether z/d or
+#        y/d or something else is a better resolution here, and other cases
+#        start getting really tricky, so I just picked one.
