There is one bracket too many. {[7/4,-9/8]} => [7/4,-9/8]

It would seem to me that this is due to solve returning a set of results. To keep the type of result consistent, a singleton set is returned. (If it were otherwise, and incorporated into a larger routine, that routine would have to check the type of result returned — set or no.)

For example, solve([(y^2) = 2],[y]) returns {[sqrt(2)],[-sqrt(2)]}.
