dialogue traces cover the owner's four reminder cases (V-579)

His two asks and his two commits, plus the check that no trace anywhere ends
with a reminder firing at the current clock. The transcript row from V-561 keeps
his verbatim words and loses its skip: "на 9" is read now, and under the commit
rule it is a question rather than a reminder.
