Subject: [PATCH] Nicer traceback at Interrupt


When Ruby is interrupted by for example Ctrl-C, the traceback looks 
something like:

> ~/ruby/installs/latest-mainline/bin/ruby ~/loop.rb
^C/home/holmberg/loop.rb:14:in `loop': Interrupt    from /home/holmberg/loop.rb:14:in `ccc'
         from /home/holmberg/loop.rb:7:in `bbb'
         from /home/holmberg/loop.rb:3:in `aaa'
         from /home/holmberg/loop.rb:18

There seems to be a "\n" missing. Then it would look like:

> ./ruby ~/loop.rb
^C/home/holmberg/loop.rb:14:in `loop': Interrupt
         from /home/holmberg/loop.rb:14:in `ccc'
         from /home/holmberg/loop.rb:7:in `bbb'
         from /home/holmberg/loop.rb:3:in `aaa'
         from /home/holmberg/loop.rb:18

Isn't this the intended layout?

Below is a patch making this change. I'm not sure if the patch is 
made the right way, or if some other case are still missnig, but the 
effect in this case seem right.
