[svn-r5740] Purpose:
Bug fix. Description: 1-D non-contiguous hyperslabs were erroneously being detected as contiguous and were causing incorrect behavior for parallel I/O benchmark (and parallel programs in general). Solution: Modified algorithm to handle 1-D case correctly. Platforms tested: IRIX64 6.5 (modi4)
