The `defspec` function signature was changed in this commit https://github.com/clojure/test.check/commit/9873cdbcb12ba84ae96b93143a0f5e63f89e3317 leading up to v0.8.0 but the
README was not updated to reflect the change.
I also removed the over-obvious comment and fixed the indentation.

I just realized that I misread the new function signature and the current README example is not invalid, as I previously thought. Feel free to close.
