To save a lot of patching for the regression tests in the devel/got
port, I added this shell function:

# compat wrapper
sed()
(
        for i; do
                arg=$1
                shift
                case $arg in
                -i)     set - "$@" "$arg" '' ;;
                *)      set - "$@" "$arg" ;;
                esac
        done
        exec sed "$@"
)

No, it doesn't handle all cases, but it is good enough in that context.
