Don't use abbreviated keys for the final merge pass. When we write tuples out to disk and read them back in, the abbreviated keys become non-abbreviated, because the readtup routines don't know anything about abbreviation. But without this fix, the rest of the code still thinks the abbreviation-aware compartor should be used, so chaos ensues.
