Cheers. Hopefully we'll get 2.15 into debian soon.
I'm working on your comments and also I have a bug fix
I'd like to get done.

Note throwing away unique file sizes first is a huge optimization.
I also sort by inodes (or path is nearly as good),
which reduces disk seeking a lot.

My method is more robust BTW (try path names with spaces)
sed -e 's/\(^.\{32\}\)..\(.*\)/\2 \1/'
Note I think uniq will get key support (like sort) at some stage.
Also debian has a specific patch for -W to compare only
the first N fields. However this is not standard and
has just been removed I understand.

Never thought of that. Hmm...
