Heres a somewhat stupid, and somewhat compact way of doing this, assuming
that three blank lines counts as an identical delimiter. It doesn't even
pretend to attempt to solve the general case of multiple character
delimiters, but instead breaks on empty lines.
tok s = map (concatMap (++ "\n")) $ break null $ lines s
(warning: untested code!)
