bug#10454: 23.3; Different result from `C-h k' and `C-h ? k'

FWIW this is due to `make-help-screen' binding `minor-mode-map-alist' to
nil.  Applying the patch below seems to fix it, but maybe someone more
knowledgeable has a better solution.  (If you want to try the patch,
make sure to recompile help.el after compiling help-macro.el).
