Fix longstanding counterbalanced bracket error
Fix longstanding counterbalanced bracket error

Two tests spanning #r2only and #r3only had imbalanced brackets, allowing
the file to still load... but not as intended:

    #r2only
    [logic! = case type? [true []]
    #r3only
    ;-- CC#2246
    [none? case [true []]]]

The opening bracket ater #r2only does not close until the end of the section.

Found during transformation script.
