Help with CTRL-M in test output on Windows

[David W. Van Couvering]

When I look at the diffs I have on some test output based on message 
text changes, I get only the lines that have changed.  But in svn diff 
it shows the old contents completely removed and new contents put in its 
place, all with ^M characters at the end of each line.

Any advice on how to address this?  I would like reviewers to see the 
actual changes made versus a global replace.

Thanks,

David
