can you "cl format" this file to clean up these parameters while here?

it might also be good to add a comment above this function to explain what
|internalformat| is.

I wanted to run "cl format" but it changes many lines, which might make reviewer
confused. Now I gladly run "cl format". :)

Yes, I think that was a good call. Thanks.
