As mentioned, the patch is sent successfully, hence the minor severity.
Searching around lead me to

I upgraded the Leap 15.4 perl-TermReadLine-Gnu-1.20 package to
perl-Term-ReadLine-Gnu-1.42-lp154 from obs devel:languages:perl and sure enough
the warning disappeared (the patch is also still successfully sent).

@Tina, Coolo and Nathan: would you be open to updating the Leap 15.4 /
SLE15-SP4 perl-TermReadLine-Gnu-1.20 package to perl-Term-ReadLine-Gnu-1.42?
