[PATCH 0/4] Make "git name-rev $(git rev-parse v1.8.3)" work

[Junio C Hamano <gitster@pobox.com>]

So here is a set of small preparatory steps to help the other topic
to allow "git describe -contains v1.8.3" omit trailing "^0" from its
output.  We do not want to prevent people from allowing "name-rev"
to convert object names other than commit-ishes.

The series should apply on 96ffd4ca (Merge branch
'nk/name-rev-abbreviated-refs', 2013-06-30).

Junio C Hamano (4):
  name-ref: factor out name shortening logic from name_ref()
  name-rev: allow converting the exact object name at the tip of a ref
  describe: use argv-array
  describe/name-rev: tell name-rev to peel the incoming object to commit first
