I would do that this way: 

s/\015\012|\012\015|\012|\015/\015\012/g;

Update: I got that order wrong, as BrowserUk suggests. I had the shorter versions on the left, and the longer on the right. The above is fixed.

It should help you with things like this to take a good, hard look at the perlre section of the standard Perl docs. You should have a copy of the standard Perl docs on your system, but if not, perlre is on search.cpan.org too.
