#202 format/pprint-logical-block bug
Seems to me that clisp pretty printer doesn't handle
correctly the variable *print-right-margin*. Here's
the dribble:
[14]> (let ((*print-pretty* t) (*print-right-margin* 100))
(format t "~@<~{~A~^ + ~_~}~:>" '(a-long-name
an-even-longer-name a-really-really-long-name)))
A-LONG-NAME + AN-EVEN-LONGER-NAME +
A-REALLY-REALLY-LONG-NAME
NIL
[15]> (let ((*print-pretty* t) (*print-right-margin* 20))
(format t "~@<~{~A~^ + ~_~}~:>" '(a-long-name
an-even-longer-name a-really-really-long-name)))
A-LONG-NAME + AN-EVEN-LONGER-NAME +
A-REALLY-REALLY-LONG-NAME
NIL
In CMUCL, it works as (I) expected.

it would be nice if you supplied the output you expected
together with the actual output replacing spaces with
underscores to avoid word wrap done by the browser.

The expected output (with _ replacing space) is, for the
first example:
A-LONG-NAME_+_AN-EVEN-LONGER-NAME_+_A-REALLY-REALLY-LONG-NAME
and for the second example:
A-LONG-NAME_+
__AN-EVEN-LONGER-NAME +
__A-REALLY-REALLY-LONG-NAME
Hope this helps.
