Whatever the limit may be, can't/shouldn't the list output always arrange the columns correctly below each other at least for such short user and group names as in my example?
Look at https://github.com/libfuse/libfuse/releases/download/fuse-3.11.0/fuse-3.11.0.tar.xz for a real life example: $ tar tvf fuse-3.11.0.tar.xz | head -4 drwxrwxr-x nikratio/nikratio 0 2022-05-02 11:12 fuse-3.11.0/ drwxrwxr-x nikratio/nikratio 0 2022-05-02 11:12 fuse-3.11.0/test/ -rwxrwxr-x nikratio/nikratio 2314 2022-05-02 11:11 fuse-3.11.0/test/travis-build.sh -rw-rw-r-- nikratio/nikratio 372 2022-05-02 11:11 fuse-3.11.0/test/lsan_suppress.txt The first two lines do not align with all the rest.
