git/branch: branches at the same commit may not be the same

in order to prevent removing the current branch git tests
the head against the specified branch name, however it is over eager,
considering any branches at the same commit hash identical.

this results in rebase not working because when finished, the work branch
is at the same commit as HEAD.
