[PATCH 0/4] Make --decorate more useful

This series is meant to (partially) replace the patch I posted in

http://article.gmane.org/gmane.comp.version-control.git/24383

Often it is useful to find out what feature came in when, to quickly
find out if some version of the software is sufficient, or if the
other person has to upgrade.

With this series applied, you can say

	git log --decorate=tag -S<some keyword> <file>

to find out what that version was, indeed you even get a human readable
name for that commit, in addition to the commit name.

Johannes Schindelin (4):
      Move add_name_decoration() and add_ref_decoration() to commit.[ch]
      Move the --decorate option from builtin-log.c to revision.c.
      --decorate now decorates ancestors, too
      --decorate: prefer shorter names
