Creating the patch for 3.0 was easy because the current master branch
points to the 3.0 branch. But adding the fix to 2.3 was a bit
difficult. I switched to the 2.3-stable branch, but that provided a
patch file of around 5 Mbyte. Probably containing all patches since
the last 2.3 stable version.
What is the correct procedure to checkout the latest and active master
version of rails 2.3?
