This is CMU CL's way of printing multiple values, e.g.

* (values t t)

T
T

Since typep is not specified to return multiple values, please ignore
the second value (which happens automatically in most circumstances,
see section on multiple values in the HyperSpec for details), until a
fix is committed for this glitch.

Regs, Pierre.
