[svn-r15124] Purpose:
bug fixes. Description: Added code to create an empty hdf5 (named h5diff_empty.h5) in order to test if h5diff compares correctly an empty hdf5 vs. a non-empty one. Tested: Tested in kagiso of h5diffgentest itself. Verified by h5dump that h5diff_empty.h5 was indeed empty. Then "h5diff h5diff_empty.h5 h5diff_basic1.h5" returned 0 (should have returned non-zero).
