@@ -30,6 +30,10 @@ is to be taken as applying to both $\py$ and $\pn$.
 All of these sets will be disjoint by construction
 (see Invariants, below).  Hence:
 
+\item[ $\set A$, $\set P$, $\ldots$ ]
+Arbitrary sets of commits.  Maybe $\set P = \p$ i.e.\ some $\py$ or $\pn$, but
+maybe not.
+
 \item[ $ \patchof{ C } $ ]
 Either $\p$ s.t. $ C \in \p $, or $\bot$.
 A function from commits to patches' sets $\p$.
