Improved the comment on the block of code the provides the performance optimization originally added by check-in [925840cfdb]. The original check-in omitted condition 4, which was the cause of bug [30027b613b]. (check-in: c6506b82aa user: drh tags: replace-fix)

Adjust filename creation in test_sqllog.c so that it uses leading zeros on counters, so that files appear in order when sorted lexicographically. (check-in: 8d67097359 user: drh tags: trunk)
