:info printing instances often isn't wanted
:info shows all instances of types/classes, which often obscures the info I'm actually interested in. See the output of e.g. ":info Show" or ":info  Maybe Int": The class and types are rather lost in between the instances. My proposal is to add an option to suppress the printing of instances. With the attached patch for 6.10.1 (although it applies to HEAD too), ":info -Show" will only print the class.
