The example for 'info pretty-printer' in the manual passes an
object-regexp in some cases, but presents output as though no
object-regexp was passed.
This commit fixes the two mistakes, in one case, fixing the output to
filter based on object-regexp, and in the other, to remove the
object-regexp from the command and leave all the output.
