I will make a second version of the patch, without
conversion as it is intentional.

I had suspicions that was the case, however, I did not find the pointers
in the code or in the commit message, that it was intentional, so I assumed
a mistake.
Maybe, it would be a good idea for me to add a comment with intent
clarification, to reduce possibility of the same confusion in the future,
while I am at it? If so, should I do it in the same patch, or make a separate one?
