Subject: scanning strings

I want to scan a string for breaks. I want to pick both the breaks and the
text in between.
If I use String#each I loose the space.
If I use String#scan, I get into a fairly involved expression with two
submatches
where the second submatch is almost exactly the negation of the first
submatch.

Is it it possible to break a string such that you get a both the match and
the text before last match, if any?

If not, wouldn't that be a useful feature in Ruby?

One simple example is processing a line at a time, but you want to keep the
break style of the source text which could be <cr>, <lf> or <cr><lf>.
