Do you want that I omit this address from the list of recipients?

Interesting …

But I got the impression that this special relationship resulted
also in a few useful side effects.

Thanks for another bit of acceptance.

Yes. - The script which I am using for the semantic patch language
(Coccinelle software) can not only find this implementation detail
but also duplicate source code generally to some degree.

> I don't think duplicate strings are a problem

They can become an issue for further considerations if inappropriate
error messages were used for example.

There are more statement combinations which can be improved a bit more.

The change acceptance is varying as usual.

I hope that my contributions can improve the affected software in some areas.

It seems that this is a topic where you got strong opinions about.

Would you accept any further adjustments around questionable jump targets?
