Yes, I missed this. It is not exactly what I want: this tells vim to ignore \n,
while I know that \n *must* be there, but this is also acceptable, thanks.

I have also a situation where last item may be empty string and it does not work
if one of the rules looks like /.*/. If I was able to match item0onLine1 using
/\nitem0onLine1/ (and add nextgroup=i0l1 to i0l0) it would be better. Or somehow
tell vim that empty string match is acceptable. I can't use `skipnl' for
previous item: it will make /.*/ match on the next line when it is not present.
