It seems that this is the intention of lines 54 through 62 in novice.el,
but it doesn't seem to work any more.
This is a regression: it still works as expected in Emacs 23.4, but no
longer in Emacs 24.3. Probably something about this-command-keys or
command-execute changed in the meantime so that the code in novice.el no
longer works as expected.
