In that case it would be useful to have an option to re-mark them:

   display -unassociated_alpha mismarked.tiff

   convert -unassociated_alpha mismarked.tiff corrected.tiff

If the input is already marked "unassociated alpha" or is not
a tiff file, the -unassociated_alpha option would do nothing.
Or what?
