With GNU Coreutils 9.4, both "test -a -a -a" and "test -o -o -o" fail:
$ export POSIXLY_CORRECT=1
$ /usr/bin/test -a -a -a ; echo $?
/usr/bin/test: ‘-a’: unary operator expected
2
$ /usr/bin/test -o -o -o ; echo $?
/usr/bin/test: ‘-o’: unary operator expected
2
According to POSIX, they should return 0.
https://pubs.opengroup.org/onlinepubs/9699919799/utilities/test.html
says for 3 arguments:
If $2 is a binary primary, perform the binary test of $1 and $3.
Here, $2 is -a and -o respectively, which are binary primaries.
And both $1 and $3 are non-null strings.
