Title: Fix build when Show has been split out from Num

`Show` was recently removed as a superclass of `Num`. This fix means that we'll have a redundant `Show` constraint on older version of base where `Show` still is a superclass of `Num`, but that shouldn't hurt. It's possible to instead fix the compilation error using an `#if` on the version of base, but GHC HEAD hasn't bumped the base version number so such a fix would have to wait until the release.
