Re: [PATCH 4/4] describe/name-rev: tell name-rev to peel the incoming object to commit first

With this on top of the other patches in this series, you would get:

    $ git describe --contains $(git rev-parse v1.8.3 v1.8.3^0)
    v1.8.3
    v1.8.3

while you can still differentiate tags and the commits they point at
with:

    $ git name-rev --refs=tags/\* --name-only $(git rev-parse v1.8.3 v1.8.3^0)
    v1.8.3
    v1.8.3^0

The difference in these two behaviours is achieved by adding --peel-to-commit
option to "name-rev" and using it when "describe" internally calls it.

Essentially a revert of [2/4] for describe-purposes, achieved by
adding an ugly command-line option to name-rev.  Before we argue any
further, let me ask: who uses name-rev (and depends strongly on its
output)?!  Our very own testsuite does not exercise it.  There are
exactly two users of describe/name-rev:

1. prompt, obviously.
2. DAG-tests, for simplification.

I really can't imagine it being useful elsewhere.
