Ok, the problem is that 22.1.3.6 does not specify that printing of bit
vectors involves *PRINT-LENGTH*. The same is true for strings
(22.1.3.4.) We could, however, use custom pprint dispatch table entries
to do the necessary truncating for us.

If you don't mind going that route, I'll happily do the work.
