- * When we cannot load the full patch-id for both commits for whatever
- * reason, the function returns -1 (i.e. return error(...)). Despite
- * the "neq" in the name of this function, the caller only cares about
- * the return value being zero (a and b are equivalent) or non-zero (a
- * and b are different), and returning non-zero would keep both in the
- * result, even if they actually were equivalent, in order to err on
- * the side of safety.  The actual value being negative does not have
- * any significance; only that it is non-zero matters.
