existing behavior of := and :[range]= are unchanged. `|` is still allowed with this usage. However, :=p and similar are changed in a way which could be construed as a breaking change. Allowing |ex-flags| for := in the first place was a mistake as any form of := DOES NOT MOVE THE CURSOR. So it would print one line number and then print a completely different line contents after that.
