When I processed the following file `src.php`:

```
<?php
include "params.php";
?>
Str 1
val a = <?=$b?>
Str 3

```

where the `params.php` file:

```
$b = 123;

```

`$ php src.php > tgt.txt`

I get the result:

```
Str 1
val a = 123Str 3

```

instead of

```
Str 1
val a = 123
Str 3

```

How shoud I solve this problem? Should I add an additional line break after `<?=b?>` through all my code?
