Made the default way, I also do not see the reason to keep larger addresses.
There is some note about `ADDR_BITS_REMOVE' but I believe it is only about the
lowest (0-2 or so) bits and the high bits should not hurt anyone.

as expected:
	The target architecture is set automatically (currently i386)

I do not believe so, it is handled everything by `LONGEST' / `unpack_long'.
