Q: What SVN URLs to use when creating patches?

I'm working on a short screencast to help explain how to contribute to 
the Ruby source code docs.  The svn URLs in the guidelines are wrong:


http://ruby-doc.org/documentation-guidelines.html

For fixing code comments and docs in the current release, what should be 
pulled from svn?

I *think* it's

   svn co http://svn.ruby-lang.org/repos/ruby/branches/ruby_1_8_6/




Thanks,


James Britt
