is-print shows empty lines

[bhase]

Hi,

I noticed is-print shows empty lines when testing strings with embedded line breaks.
Example:

(is-print (format t "Hello~%World!")
"Hello
World!")

I would expect that this simply shows a green tick but it puts an empty line before. Is this desired?
I am testing multi-line output and this is distracting as for every line an empty on is shown in output.

Regards,
Benjamin

I couldn't reproduce it.
What version of Quicklisp dist do you use?

Give me the result of (ql-dist:dist "quicklisp") and (ql:where-is-system "prove").
