revert changes to help(help); those should probably be a separate PR

-            help - Interactive Help
-            =======================
-
-            The built-in help function implements an interactive help utility.  You
-            can make use of it in a few different ways:
-
-            * Calling help() with no arguments starts an interactive help session.
-
-            * The behavior of help(x) depends on x's type:
-
-                * If x is a string, help(x) provides information about the given
-                  topic.  For example, help("class") will provide information about
-                  the "class" keyword, and help("math.sqrt") will provide
-                  information about the "math.sqrt" function.
-
-                * If x is a class or a built-in type, help(x) provides information
-                  about that type.  For example, help(str) will provide information
-                  about the str type.
-
-                * For all other objects, help(x) prints information about x's type.
-                  For example, help(20) will provide information about the int type.
