+       * help-fns.el (help-fns-describe-function-functions): New
+       variable to call functions for augmenting help buffers.
+       (describe-function-1): Remove explicit calls to
+       `help-fns--compiler-macro', `help-fns--parent-mode' and

+       but to augment existing help buffers.  Remove optional second
+       argument.  Create proper button for file location.  Rewrite
+       function to use `insert' instead of `princ' and `prin1' where

+       `eieio-describe-constructor' and `eieio-describe-generic', resp.

+       buttons.
+       (eieio-help-find-method-definition)
+       (eieio-help-find-class-definition): Also accept symbols as
