When using result formats list, ul, or ol the additional query parameters are forcibly surrounded by parentheses, as documented here:
Parentheses may be desirable in some circumstances, but certainly not all circumstances. For example, the query result output:
1957 (blue convertible soft-top Chevy)
Would be more readable as:
1957 blue convertible soft-top Chevy
Parentheses should be optional, and perhaps controllable just like the separator/delimiter when using the sep= parameter.
