[antlr-interest] Lists of one & rewrite rules

I currently have a rule like:
orExpr : andExpr ( or andExpr )* ->
^(OR_OP andExpr*);
That means I always get a tree like:
(OR_OP expr ...)
but for a singleton I'd like just the expression
instead of:
(OR_OP expr)
How do I do that in the re-write rule? Can I test for
just one item in the list ?
