I was already aware that my patch only handles the 's' command, but people came up with very interesting combinations of commands and sed command line flags that would mutate (or not) the input.
I think what is left is me asking the developers of sed if adding such a functionality in a reliable, efficient, and maintainable way can even be considered possible?
