There is another mention of "sha1" in the rewritten text. Intended or an oversight?

-#define ENTRY_SHA1(e) (((e)->mode && S_ISDIR((e)->mode)) ? (e)->oid->hash : 
NULL)
-       buf0 = fill_tree_descriptor(t+0, ENTRY_SHA1(n + 0));
-       buf1 = fill_tree_descriptor(t+1, ENTRY_SHA1(n + 1));
-       buf2 = fill_tree_descriptor(t+2, ENTRY_SHA1(n + 2));
+#define ENTRY_OID(e) (((e)->mode && S_ISDIR((e)->mode)) ? (e)->oid : NULL)
+       buf0 = fill_tree_descriptor(t + 0, ENTRY_OID(n + 0));
+       buf1 = fill_tree_descriptor(t + 1, ENTRY_OID(n + 1));
+       buf2 = fill_tree_descriptor(t + 2, ENTRY_OID(n + 2));
  #undef ENTRY_SHA1

This whould be #undef ENTRY_OID.
