Ah, but what if the print statement's indented?

#!/usr/bin/perl -wT
use strict;

while(<DATA>) {
    chomp;
 
    if( m{^(\s+)(?:print\s\"(.*)\"\;)$}g ) {
        splittor($1,$2);
        next;
    }

    print $_."\n";    
}
exit;

sub splittor {
    my $indent = shift || '';
    my $str = shift;

    # quick hack for accurate count
    my $tabcount=0;
    $tabcount++ for ($indent =~ /\t/g);    

    # assuming tab == 4 spaces
    my $maxlength = 60-length($indent)-($tabcount*3);
    my ( @str ) = grep $_, split /(.{1,$maxlength})/, $str;

    print "${indent}print ";
    print join ( ",\n$indent\t", map {'"'.$_.'"'} @str );
    print ';'."\n";

    return undef;
}

or something like that (untested).
