            Bug ID: 267826
           Summary: awk(1) functions or(), and() and xor() broken when
                    used with more than 2 args

repro case

The functions or(), and() and xor() are defined in the manpage to be able to
take multiple parameters: "There must be at least two values."

Specifying more than 2 is broken after an upgrade to 12.3 (works on 12.2):
1) an incorrect warning is printed "awk: warning: function has too many
arguments"
2) results are wrong, 3rd and subsequent arguments are simply ignored.

Attached is a repro file.
