Changing the interpretation type of data under the cursor moves the
cursor to the beginning of BB cluster. When cursor is set to an
inode the cursor is offset in BB buffer. However, this offset is not
considered when type of the data is changed - the cursor points to
the beginning of BB buffer. For example:
$ xfs_db -c "inode 131" -c "daddr" -c "type text" \
-c "daddr" /dev/sdb1
current daddr is 131
current daddr is 128
