Merge branch 'jc/symbolic-ref-no-recurse'
After checking out a "branch" that is a symbolic-ref that points at
another branch, "git symbolic-ref HEAD" reports the underlying
branch, not the symbolic-ref the user gave checkout as argument.
The command learned the "--no-recurse" option to stop after
dereferencing a symbolic-ref only once.
* jc/symbolic-ref-no-recurse:
symbolic-ref: teach "--[no-]recurse" option
