[svn-r2984] Purpose:
	Bug fix
Description:
	The code for determining what a string should print out if it was
	declared as H5T_STR_NULLTERM (C strings), H5T_STR_SPACEPAD
	(Fortran strings), or H5T_STR_NULLPAD (print null characters to
	the end of the line) was mucked. A user had a problem with it and
	suggested a change, but the change didn't seem to work properly.

	Also, if the string was H5T_STR_SPACEPAD, it could have stopped
	when encountering a NULL even if it hadn't gotten to the end of
	the string.
Solution:
	Reworked the code to make it more understandable what's happening
	and to add in support for H5T_STR_SPACEPAD which may have been
	missing before.
Platforms tested:
	Linux
