From: Arnaud Bertrand <xda@xxxxxxxxxx>
Add the branchname in the commit header before the commit message
the following line is added:
branch <branchname>
where <branchname> comes from the function resolve_ref_unsafe("HEAD",...)
without the prefix refs/heads/
A placeholder is added to the pretty format "%Xb" to print the branch information,
X if for "extra-header" and can be use in the future for new features
b is of course for "branch"
the %Xb returns an empty string when branchname information is not found
