Re: [1.8.0] git checkout refs/heads/foo checks out branch foo

Proposal:

'git checkout refs/heads/foo' (or 'git checkout heads/foo' for that
matter) does not check out the branch, but instead detaches HEAD at
foo.

Yes, and it is deliberately so as it is a guaranteed-sure way for scripts
to work around potential ref ambiguity when talking about the branch
called 'foo' to spell it out with leading refs/heads/.

As long as you do not break scripts that guard against breakage you are
proposing by saying "refs/heads/foo^0", we are Ok with the proposal, I
think.

Migration plan:

Make 'git checkout refs/head/foo' emit a warning in the next 1.7.x
explaining that its semantics will change in 1.8.0. Then change the
behavior in 1.8.0 and remove the warning.

Reasonable.

Thanks.
