 * Descriptipn:
 * 	Given the lvname_info *, which contains all the mvals of all
 * 	subscripts and the name itself, of a local variable node,
 *	this will format the entire local variable key
 * Input:
 *	lvnp: Pointer to the structure of a local variable
 * 	buff: Buffer where key will be formatted
 * 	size: Size of buff
 * Return Value:
 *	End address upto which buffer was  used to format the key
 *	(Needed for the length calculation in caller)
