+echo ------------ Testing chains ------------
+rem The chain operators have the following bottom-up precedence:
+rem 'else' precedes nothing and matches the closest unmatched 'if' in the same bracket depth
+rem '&' precedes 'else'
+rem '||' precedes '&' and 'else'
+rem '&&' precedes '||', '&' and 'else'
+rem '|' precedes '&&', '||', '&' and 'else'
+rem
+rem Example: 'if 1==1 if 2==2 if 3==3 a | b && c || d & e else f else g' is interpreted as
+rem 'if 1==1 (if 2==2 (if 3==3 ((((a | b) && c) || d) & e) else f) else g)'
