[svn-r5740] Purpose:

Browse Source 
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)
