Return carriage on annotated parameters

Hello,

This is a **low priority issue** but while printing annotations within parameters I've noticed it adds a return carriage. Here is what I mean:

I intend to get this:
```JAVA
public Content pop(@PathVariable int proxy_id) {
```

but with the following code:

```JAVA
//add proxy id to the parameters of the method
CtParameter proxy_int = launcher.getFactory().createParameter();
proxy_int.setSimpleName("proxy_id");
proxy_int.setType(launcher.getFactory().createReference("int"));
CtAnnotation a = launcher.getFactory().createAnnotation(); // creation of the annotation variable

// Type of the annotation
CtTypeReference type = launcher.getFactory().createReference("org.springframework.web.bind.annotation.PathVariable");
a.setType(type);
a.setAnnotationType(type);

proxy_int.addAnnotation(a); // add annotation to the parameter.
method.addParameter(proxy_int); // add the parameter to the method.
```

I get this:

```JAVA
public Content pop(@PathVariable
int proxy_id) {
```

I assume the prettyprinter adds the return carriage because it also does so when adding an annotation for a method or a class, where the return carriage is expected for clarity. While it still works fine it can be a little hard to read when I have a method with 2-3 annotated parameters. Am I doing this wrong, or is this working as intended? Thank you.

```JAVA
@GetMapping("/ContentProviderService/{id}/test")
public void test(@PathVariable
int proxy_id, @RequestBody
Screen screen);
```
