That could be what you'd like to do in that case, but it doesn't have
to be what everyone will want to do.  Other possibilities include
turning on longlines mode there, or turning on so-long-mode, or
killing the buffer.  And I'm sure there could be other possibilities
that make sense in some cases.

IOW, I'm completely unsure that there's one-fits-all modus operandi
when that happens.
