[RESEND,0/2] status: improve info for detached HEAD

Message

When a repository is cloned using "git clone -b" and a tag is specified,
HEAD is automatically detached. As a result, "git status" shows
"currently not on any branch", which is not very useful.

Teach "git status" to generate the "HEAD detached at" message in this
case as well, in a similar way to when a tag is checked out.

In the case of "git checkout", the name of the ref that was checked out
is retrieved from the reflog; for "git clone", the name of the ref isn't
present in the reflog entry, so we use the abbreviated hash instead.
This is also consistent with the "detached HEAD" advice.
