Hello! I agree with Raphaël's comments. The wording of this error could be improved a bit.
In https://mariadb-team.pages.debian.net/-/mariadb-10.3/-/jobs/929803/artifacts/debian/output/lintian.html I got E duplicate-globbing-patterns mysql-test/mysql-stress-test.pl in lines 213 467 467 E duplicate-globbing-patterns storage/innobase/fts/fts0pars.cc in lines 590 590 E duplicate-globbing-patterns storage/tokudb/PerconaFT/third_party/xz-4.999.9beta/lib/getopt_int.h in lines 769 800 E duplicate-globbing-patterns strings/strxmov.c in lines 355 355 E duplicate-globbing-patterns strings/strxnmov.c in lines 355 355 E redundant-globbing-patterns [client/* client/echo.c] for client/echo.c E redundant-globbing-patterns [mysql-test/mysql-stress-test.pl mysql-test/mysql-stress-test.pl] for mysql-test/mysql-stress-test.pl E redundant-globbing-patterns [storage/innobase/fts/fts0pars.cc storage/innobase/fts/fts0pars.cc] for storage/innobase/fts/fts0pars.cc E redundant-globbing-patterns [strings/strxmov.c strings/strxmov.c] for strings/strxmov.c E redundant-globbing-patterns [strings/strxnmov.c strings/strxnmov.c] for strings/strxnmov.c -> 6 errors would have been enough, now there are 10 -> some have identical line numbers twice Also, I was unable to find it's documentation at the usual location at https://lintian.debian.org/tags/duplicate-globbing-patterns.html Never the less, the usability was good enough that I was able to fix the issues and now Lintian passes for this package. This is just a minor improvement suggestion.
