Quincey Koziol ac212d18f8 [svn-r19725] Description: 
Add a little bit of extra info to the output from h5debug when
displaying global heaps, and make it dump the file's superblock again when
an address is not given on the command line.

Tested on:
	FreeBSD/32 6.3 (duty) w/debug
	(too minor to require h5committest)
