Build Identifier: Version: Indigo Service Release 1

If I edit the last rule of the attached grammar, and hit Return after the last
semikolon, a '}' is added and marked as syntactically wrong.
Placing spaces before or after the | cures the problem, but I have not found out what the system is.  Editing the file and undoing the change made
the problem vanish as well.

See http://www.eclipse.org/forums/index.php/mv/msg/277439/780782/#msg_780782


Reproducible: Sometimes

Steps to Reproduce:
1.Enter the grammar. I was able to reproduce the problem a few times with:

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

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

Model:
	x=st1;
terminal st1:
	'"' ( !('\\'|'"'|'$'|'['|']'|'{'|'}') )* '"'; 

and then at some point it started working as expected :-(
2. go to the end of the file, hit enter
3. get a closing curly brace two lines lower with a red wavy underline.
