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.
