It seems on FreeBSD sed replaces a backup file.

This is a regression I introduced. (The FreeBSD code used rename, instead of link. I changed that because the rename method left the possibility of exiting without leaving even the original file intact.)
Fortunately, the fix is super easy.

Btw, -i requires an argument. Apparently GNU sed doesn't. Not sure how that is achieved, but this might be a GNUism that we don't quite achieve.
