I ran git update-server-info on the server machine. I read about this
and thought I had made the necessary change to add it as a post commit
hook. I guess not (so will double check). However, something is still
not quite right upon cloning:

> git clone https://mysite/git/project.git
Initialized empty Git repository in /home/matt/git-repos/project/.git/
Checking out files: 100% (26747/26747), done.

> git branch -a
* master
  origin/HEAD
  origin/custom
  origin/master
  origin/upstream

> git checkout upstream
error: pathspec 'upstream' did not match any file(s) known to git.

So it seems that the cloned repository is now aware of the branches
(improvement) but I'm still unable to switch to a branch.

This is probably now a case of me reading the manual but I'd appreciate
your thoughts nonetheless.

Thanks for your continued feedback,
