It's in _create_runperl() isn't it?
If you pass a prog, then it sets
$args{progs} = [$args{prog}]
and then, since you now have progs, it builds a command from a series of
-e options:
foreach my $prog (@{$args{progs}}) {
if ($is_mswin || $is_netware || $is_vms) {
$runperl .= qq ( -e "$prog" );
}
else {
$runperl .= qq ( -e '$prog' );
}
}

If you do, then a warning about embedded newlines would also be useful.
That's tripped me up a couple of times, e.g.
