These instructions failed for me when I got to the command:
git subtree pull --squash --prefix=projects/dkan http://git.drupal.org/pr
I got an error message that read:
fatal: ambiguous argument 'HEAD': unknown revision or path
not in the working tree.
Use '--' to separate paths from revisions
Working tree has modifications. Cannot add.
It seems to me that the instructions for doing this should hew more
closely to the git subtree manual instructions. In other words, you
would start with something like:
git remote add dkan_remote http://git.drupal.org/pr
git fetch dkan_remote
git checkout -b dkan_branch dkan_remote/7.x-1.x
