I see the bug report now ! Thanks for the fix. Long story short I've
had this bug for many months, I eventually decided to report it since
I could reproduce it at work. The thing is that system at work is
Ubuntu 19.04 with:

$ apt-cache policy ncurses-base
ncurses-base:
  Installed: 6.1+20181013-2ubuntu2
  Candidate: 6.1+20181013-2ubuntu2
  Version table:
 *** 6.1+20181013-2ubuntu2 500
        500 http://fr.archive.ubuntu.com/ubuntu disco/main amd64 Packages
        500 http://fr.archive.ubuntu.com/ubuntu disco/main i386 Packages
        100 /var/lib/dpkg/status

No the issue is that I did not pay attention I cannot reproduce on my
Debian/stable at home anymore. My bad.

Neet trick. I'll override the terminfo for my Ubuntu system at work.
