In some cases it might happen that you have an argument that deep down
somewhere has an array with a lot of entries (think thousands). Now
before we would just happily print them all. Which would fill the log.
Now it will just print the first 5. And add a line that there are N
more.
If you are on debug level we will still print them all.
