On the other hand, we may want to make sure that the new option does not disturb CR in the middle of the line, so we may be better off leaving double per-cent unanchored, but allow replacing more than once on a line, i.e. "s/%%/$(printf \\015)/g". If we were to go to the latter route, we'd want to try a file with a CR in the middle of the line (without a CR at the end of any line) and make sure we won't warn or strip.
