uniq(1) used to have an option for checking only a certain number of fields. I have since noticed that some scripts I wrote some time ago have stopped working because the -W / --check-fields=N option has disappeared. Can it please be put back in?

It's still there in the latest stable version, 5.96:
$ uniq --version | head -n1
uniq (GNU coreutils) 5.96
$ uniq --help | grep check
  -w, --check-chars=N   compare no more than N characters in lines

not --check-chars=N, I'm talking about --check-fields=N.
I am happy to write a patch to do so if no-one else wants to do it. Is there a reason why it disappeared?

Probably because you switched systems or PATH, and are no
longer using the GNU coreutils version of uniq.

I upgraded recently from Debian Sarge to Ubuntu Dapper, and I noticed that the -W (note the caps!) flag had disappeared. Maybe it was a Debian distro patch. Paul Eggert has mentioned that upstream uniq has never had a -W flag. Would you be receptive to a patch? I'm happy to write one.
