So basically the proposal there is to support --suppress-matched so that you could then do:

uniq -w1 --unique=separated --all-repeated=separated | csplit --suppress-matched '/^$/' '{*}'

The caveat with that though is that uniq would benefit from better field selection, which is also on the TODO list.

uniq with fields is indeed useful, but the example above seems a bit long for something that can be acheived natively with just csplit (IMHO) - what do you think ?
