You haven't told git where to find the repository itself. GIT_WORK_TREE
is about saying "here are my work tree files", but it is explicitly not
about "here is where my .git directory is". That lets you keep the two
in totally separate locations. E.g., you could do something like
tracking /etc, but keep your .git directory in /var.

For your case above, you would want to also

  export GIT_DIR=/Users/ron/devel/gittest/.git

though since you have a fully formed repository, I don't think there is
really any advantage over just doing:

  cd /Users/ron/devel/gittest && git $whatever

though perhaps that is because this is not a real use case, but rather
just you trying to figure out the feature. :)
