You can add overlays to the buffer with :before-string or
:after-string properties.  Not sure if this is also possible with text
properties, though.  If you need to use overlays, then you need to
move the overlays when the buffer changes...

longlines.el uses a similar mechanism to show hard newlines with the ¶
symbol.  But I didn't write it, so I don't know how it is done.
