[RFC/PATCH 1/2] for-each-ref: add new format 'refbasename'

fot-each-ref's refname format outputs each ref in its full format, e.g. 'refs/heads/foo' and 'refs/tags/bar'. However, there are tools that need only the last part of the refname, e.g. only 'foo' and 'bar'. Such a tool is git's bash completion script, which spends considerable amount of time removing the unneeded parts from for-each-ref's output.

Therefore, we introduce a new for-each-ref format called 'refbasename', which strips everything before and including the second '/' in the ref's name from the output.

  I assumed that refs always look like 'refs/{heads,tags,whatever}/foo',
  hence this patch breaks if a ref might look like 'refs/foo' or just
  'foo'.  But can I really rely on that?
