Hello coreutils maintainers, test in coreutils 8.30 supports the unary -a test (is the same as -e) but this is not listed on the manpage (in bash 4.4.12 "help test" does list it).
I can imagine good reasons to kick out the unary -a but I think it then should be kicked out of program and man page (or it should be listed in the man page, maybe as deprecated). Best regards, Martin
