----------------------

./src/H5D.c
./src/H5Fistore.c
./src/H5Fprivate.h
	Fixed a couple things for parallel hdf5 that I broke with the
	last checkin.

./src/H5Ofill.c
	If no fill value is specified it isn't added to the object
	header.

./tools/h5ls.c
	Added a line-feed after `Unknown object' is printed.

./tools/h5tools.c
	Fixed printing of scalar values.  Need to still track down a
	failed assertion when H5Sselect_hyperslab() is called with a
	zero size....
