Quick fix: none smaller than this (the bridge fix alone leaves a covered merge needing the bridge). Thorough fix (chosen): loadNewest asks takenAlready (already used for group members) before loading the newest merge of a repository; at or behind taken it is marked Covered, said once in the log, and never read. A merge whose ancestry cannot be asked is read as before. Test: a row pair behind/ahead of taken with a bridge that cannot answer.
