In the tests FORMAT.:T.1 FORMAT.:T.2 FORMAT.:T.3 you assume that FORMAT ~10:T
does nothing if the stream is not a pretty-printing stream.
CLISP honors the FORMAT ~10:T even when the stream is a string-stream.
Could you please fix the tests?

Interesting: These two pprint-tab forms don't specify a stream, therefore the
stream on which these forms operate is unspecified:
- The PPRINT-TAB description just says
"stream---an output stream designator"
and the PRIN1 description says
"output-stream---an output stream designator. The default is
- The HyperSpec/Body/glo_s.html#stream_designator description says that
nil denotes "the value of *standard-output* for output stream designators".
Anyway, this is irrelevant here, because CLISP's FORMAT ~T implementation binds
*STANDARD-OUTPUT* to an intermediate pretty-printing stream, while doing
PPRINT-TAB. So it is really capable of honoring FORMAT ~10:T.
