hdf5/test/trefer.c
Quincey Koziol c50c23d387 [svn-r14129] Description: 
Add H5O{set|get}_comment routines, which were overlooked before.

	Move H5G{set|get}_comment routines to deprecated code section,
replacing internal calls with H5O{set|get}_comment.

Tested on:
	FreeBSD/32 6.2 (duty)
	FreeBSD/64 6.2 (liberty)
	Linux/32 2.6 (kagiso)
	Linux/64 2.6 (smirom)
	Solaris/32 5.10 (linew)
	AIX/32 5.3 (copper)
	Mac OS X/32 10.4.10 (amazon)
