Students, in particular, should get used to frequent autoindenting
rather than manually inserting spaces. Then, if the indentation of a
section ever looks different than you felt it should, that's where
your mistake is.

As for when to do it, I think a nice compromise between "force
autoindent-all" and "don't perform magic behind the student's back" is
to track the dirty state of autoindentation, and disallow the "run"
button until "autoindent-all" is clicked.
