"in" on sequel causes an SQL error

[adamgotterer]

I assume this project is pretty dead due to the last commit being many years ago. But I figured I'd submit this bug anyways.

Given the URL ?some_id[in]=1,2,3, It converts in Sequel to SELECT * FROM "some_table" WHERE (some_id IN (('1', '2', '3'))) which causes a type error. The IN section should actually be IN('1','2','3'), with only a single paren.
