     the most recent revision.
 
+    The reserved name "null" indicates the null revision. This is the
+    revision of an empty repository, and the parent of revision 0.
+
+    The reserved name "." indicates the working directory parent. If
+    no working directory is checked out, it is equivalent to null.
