This has to do with the Posix rules for `test'. The behavior is strictly
defined for cases where the number of arguments is 0-4 (and these cases are
documented in the description of `test' in the bash documentation). For
five or more arguments, the expression is parsed according to precedence,
and `(' introduces a parenthesized subexpression.
