NOTE: the diff for mysql-test/r/innodb.result in this ChangeSet looks
empty but the line:

Data truncated for column 'c' at row 1

is present in annotated mysql-test/r/innodb.result@1.215 [1]
and not present in annotated mysql-test/r/innodb.result@1.216 [2] so it
must have been deleted in the above ChangeSet.
