    So how hard would it be to make `move-to-column' and `current-column'
    work properly in this respect?

move-to-column could be made to do what line-move-to-column now does.
I am not sure that is a good idea, because I am not sure it is a clean
general solution to what to move-to-column ought to do with invisible
text.
