	* src/ramdisk.c: The "from" and "to" locations are calculated as
	the start of the block within the ram that data is to be transferred
	from/to for reads and writes respectively.  However, within
	the loops, the "from" and "to" locations are never updated.  The loop
	should have been updated as:
	    from += rd->block_size;
	and
	    to += rd->block_size;
	within the for loops in the ramdisk_read and ramdisk_write routines,
	respectively.
