Interesting... I've never made it down to the rational section of test
and till now never really thought about the issues with -a and -o.

They should probably put a bigger warning at the main section of the
documentation.

The `-a' and `-o' operators are included in the `test' builtin
documentation. They're not deprecated, per se -- they don't really come
into play unless test is given four or more arguments.

Guess that's why bash doesn't even mention these operators nor ( ) in
test?

It does.
