ah, indeed. I did not do enough testing (the R variant of the bug is more 
likely to produce a syntax error, and therefore to show immediate symptoms). 

This should now be fixed in our SVN version (http://p.sf.net/rkward/svn). It 
would be nice, if you could do some testing, too. Let us know, if you find any 
further issues.

Hm, I could have sworn the bug shows only with the curly brackets, but you are 
right, it also shows without. No idea what might be the cause, here. Anyway, 
the take-home-message is:
* Pasting any larger pieces of code into a plain R console is buggy.
* RKWard is not (any longer) affected by this bug / these bugs.

Yes, probably.
