We already have such a text property (display-line-number-disable),
but it cannot help here, because you do want the line of buffer text
that follows the after-string to have a number.  Only the after-string
should not have a number.

Those modes didn't pay attention to overlays at all.

Anyway, people are welcome to work on some tweak in these cases.  It's
a bit tricky, because the display engine only ever looks at a single
screen line, but maybe someone will have a clever idea.
