v4 of this patch series can be found here :
http://article.gmane.org/gmane.comp.version-control.git/272285

This is a continuation of my GSoC project to unify git tag -l, git
branch -l and for-each-ref. Continued from this patch series :
http://thread.gmane.org/gmane.comp.version-control.git/271563

Changes in v5:
03/11: grammatical changes.
04/11: grammatical changes.
05/11: remove unnecessary if statement and remove caps used in commit message.
06/11: use xcalloc instead of using a commit_list as we know the size
of the array.
07/11: s/<object>/[<object>]/ as the object is optional.
08/11: rename parse_opt_commit_object_name() to parse_opt_commits().
09/11: make branch.c also to use the macros.
11/11: s/<object>/[<object>]/ as the object is optional.

Thanks to Matthieu, Christian, Junio and Eric for the input on the
last iteration.
