Correct.  Each primary returns 'true' or 'false', and the first 'false'
primary causes process to end for that file.

     The primaries may be combined using the following operators.  The
     operators are listed in order of decreasing precedence.
     expression -and expression
     expression expression
          The -and operator is the logical AND operator.  As it is
          implied by the juxtaposition of two expressions it does not
          have to be specified.  The expression evaluates to true if
          both expressions are true.  The second expression is not
          evaluated if the first expression is false.
