A wait what do you mean you have not set up numbered backups, maybe this already is
the difference. I will come back to the point later

Which is the expected behavior.

I did and yes the problem also occurs in git, so the
problem is my setting not git/mercurial, which is good.

I have a relatively recent version of GNU emacs master, but cannot find
the variables make-backup-by-copying. Could you please explain.


I had however 

backup-by-copying set nil, now it is t, but still the behavior is the
same.

So maybe it boils down to what you said at the beginning

   > I'm not using numbered backups
https://www.gnu.org/software/emacs/manual/html_node/elisp/Numbered-Backups.html

Ok I had 

Version-control set  to t.
I changed it to nil: no change 
I changed it to never: emacs now makes test.tex~ instead of test.tex.~1~

I am running out of ideas.

Where is the mistake?
