And I should have looked at current_column_1, too.  Seems that the
only interesting text properties here are 'invisible' mostly.

Anyway, here is another idea for "Emergency wrapping": use
`vertical-motion' for checking that the wrap positions are still in
the physical screen line.  Maybe this should be done only if used
interactively, though.

I was at first afraid that this would wreak havoc when the windows are
split horizontally, but that case could be catered for by binding
truncate-partial-width-windows to t.
