wt-status: don't skip a magical number of characters blindly

rscharfe · gitster · commit 8d8325f8ee3e · 2015-11-01T09:58:20.000-08:00
Use the variable branch_name, which already has "refs/heads/" removed,
instead of blindly advancing in the -&gt;branch string by 11 bytes.  This
is safer and less magical.
