A tooltip may be too obscure as the sole source of information (hardly
surprising since that is pretty much generally true for tooltips).  As
additional info, it certainly is helpful.

We already put tooltips on raw/illicit bytes in utf-8 buffers.  It
seems like it would be natural to do this for unsaveable bytes, too.
Probably overlays rather than text properties are appropriate for
that, however, since the unsaveability is rather a property of the
buffer (and its encoding) than the text: with bad utf-8 bytes, it is
rather a text property, in contrast.
