No demarcation but in KeyValue, we keep row, column family name, column
family qualifier, etc., lengths and offsets so the comparators on ly
compare pertinent bytes.

If you doing a prefix scan w/ row1c, we should be starting the scan at
row1c, not row1 (or more correctly at the row that starts the block we
believe has a row1c row in it...).
