Bug 346651

Grammar (| is cursor position):

grammar org.xtext.example.mydsl1.MyDsl with org.eclipse.xtext.common.Terminals

generate myDsl "http://www.xtext.org/example/mydsl1/MyDsl"

Model:
	greetings+=Greeting*;

Greeting:
	'Hello' name=ID '!' other=[Greeting]?;

|

Choose 'INT' proposal and you'll get:

grammar org.xtext.example.mydsl1.MyDsl with org.eclipse.xtext.common.Terminals

generate myDsl "http://www.xtext.org/example/mydsl1/MyDsl"
import "http://www.eclipse.org/emf/2002/Ecore" as ecore

  <-- this blank line is not necessary
Model:
	greetings+=Greeting*;

Greeting:
	'Hello' name=ID '!' other=[Greeting]?;

terminal INT returns ecore::EInt:
	
;

=================================
Another case with unwanted blank lines:

Model:
	greetings+=Unknown*;

Greeting:
	'Hello' name=ID '!' other=[Greeting]?;

Choose quickfix 'Create rule Unknown' and you'll end up with:

Model:
	greetings+=Unknown*;

Unknown:
	
;

  <-- this blank line is not necessary
Greeting:
	'Hello' name=ID '!' other=[Greeting]?;
