>> On Emacs 29 and earlier, with `-Q`, we have:
>> 
>> (pp-to-string "foo")
>>   => "\"foo\""
>> 
>> On master with `-Q`, we get an extra newline at the end of the string:
>> 
>> (pp-to-string "foo")
>>   => "\"foo\"
>> "

Is that a problem?
I also see that the old `pp-to-string` added that same extra newline for
slightly more complex input:

    ELISP> (pp-to-string '("foo"))
    "(\"foo\")
    "
    ELISP> 

> Stefan, is this due to your changes in pp?

Yes.
