Re: [PATCH] sed: add --error-if-unmodified to error out if input was not

As I was pointed out yesterday by my fellow Gentoo developers, this patch barely scratches the surface of what could constitute sed mutating the input and misses a lot of cases. So please consider this an idealistic but naive approach. :)

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?
