Re: specifying revision - how to enforce matching a tag/branch-name or revision only

Hi,

I discovered an interesting problem when using `git checkout` to which
I couldn't find a good solution. We have an automatic system trying to
checkout a branch only when it exists. To do so we check whether `git
rev-parse` finds a commit for given branch name:

git rev-parse "${BRANCH_NAME}"  || git rev-parse "refs/remotes/${UPSTREAM}/${BRANCH_NAME}"

Unfortunately somebody used the branch name "add-gcc10" and `git rev-parse` which didn't exist on one repository. However `git rev-parse`
also supports to parse the `git-describe` format which resulted in checkout a commit starting with "cc10".

Can't you prepend "refs/heads/" to BRANCH_NAME to disambiguate?
