the tags have to be zero characters long for the wrapping purposes.

That's more difficult. I would probably do it like this: 

$_ = "foo<span>bar</span>bazqux<span>quux</span>";

my $c=0;
s( (<span>|</span>|.) ) {
    my $s = $1;
    $s =~ m!</?span>! ? $s : $s . (++$c % 4 ? '' : "\n");
}sxge;

print;
print "\n";

That will show you how it works but in your case you'll need to change that '4' to '80' in the ++$c % 4 part.

Update: added /s to regex so . would match "\n" as well.
