The lintian Debian tool is complaining about:
  'W: mariadb-test: manpage-has-errors-from-man
  usr/share/man/man1/mysql-test-run.pl.1.gz 246: warning [p 2, 6.0i, div
  '3tbd1,1', 0.3i]: can't break line'

See: https://salsa.debian.org/faust-guest/mariadb-10.3/-/jobs/431900

The following command permits to catch the problematic lines:
  $ groff -man -Tascii ./mysql-test-run.pl.1 | less

Closes #1419
