Hi 

On one of my systems one of these (non-broken) tests fails. I am not
sure whether I messed up my emacs/environment when doing stuff remotely
recently so it could just be my system

It's this test: I get an extra newline after the UFT8_YEN. 

This is with emacs 23.4.1 on a Debian wheezy(ish) system.

But as said it could be my fault: I think some odd things happened when
I tried to install emacs 24 and 23 simultaneously to help testing
things.

Best wishes
