Given the following Xtext grammar:

grammar org.xtext.example.mydsl.MyDsl with org.eclipse.xtext.common.Terminals

generate myDsl "http://www.xtext.org/example/mydsl/MyDsl"

Model :
  (elements+=Element)+
  (
    c='c'       &
    (d='d'      )?
  )
;

Element :
  '(' (AElement | BElement) ')'
;

AElement : elem='a';
BElement : elem='b';

and the following formatter rules defined in method configureFormatting:

ModelElements modelAccess = f.getModelAccess();
c.setLinewrap().before(modelAccess.getCCKeyword_1_0_0());
c.setLinewrap().before(modelAccess.getDDKeyword_1_1_0());

ElementElements elementAccess = f.getElementAccess();
c.setNoSpace().around(elementAccess.getLeftParenthesisKeyword_0());
c.setNoSpace().around(elementAccess.getRightParenthesisKeyword_2());

and the following model:

(a)(b)
c

I would execpt that formatting has no effect, i.e. that the model is already correctly formatted. But the outcome is the following:

(a)(b)c

Is this a bug? I would have expected a linewrap before 'c'.


Reproducible: Always

Steps to Reproduce:
1. Define grammar
2. Implement formatter
3. Create 'test.mydsl' and format given text
