Since you're renaming the function, I suppose removing the function
would also work, which would not create any "dead code".  But that
probably requires a separate patch file, which will break more easily
on an update.

So long story short:  This is OK to me, even though I don't like
producing code that won't be run anyway.

I've seen the '\n' on an earlier patch as well.  Why is it neccessary?

Otherwise, LGTM!

Kind regards,
