Ruby 1.9 source code does not compile when cloned from a git-svn gateway
I maintain an git-svn gateway repository. I have a server which uses git-svn to checkout the Ruby source code, while I use 'git clone' to clone the repository on my local development machine. The Ruby 1.9 source code currently fails to compile when using this setup because it expects that one is using git-svn upon detecting git. The attached patch fixes this problem.
