This is hopefully a simple issue, but google has not found me an answer  
yet.

I’m just starting to learn Ruby, and my IDE of choice is Emacs. I’ve  
installed the emacs extensions, and can run “rdebug” within a ruby  
buffer and it does the right thing, but all of the RDEBUG frames display  
‘^M’ at the end of the lines. While not a big issue, it does clutter  
the spaces unnecessarily.

How can I disable/remove/hide the ^M in these buffers?

Thanks!

I figure it’s some sort of translation issue, but it only appears in the  
RDEBUG emacs frames, and doesn’t appear in the Ruby or Debugger frames.  
Googling gives various hits for search-and-replacing in text files, but  
turns up nothing about debugging buffers.
