Also the commit object names (hence "describe" output) do not

However, I suspect that we could do better with Shawn's new
fangled describe implementation that actually counts the
distance between what is described and the tag.  We could add
"number of commits since the tag" somewhere, to describe:

        v2.6.20-rc5-256-g419dd83
        v2.6.20-rc5-217-gde14569

to say that the first one has 256 commits accumulated since the
given tag "v2.6.20-rc5" and the second one has only 217
commits, to get the sense of how busy the development activity
is.

Is it useful?  That is something I am not sure.

I find it usefull. I even suggested it in November:

One problem I see with this scheme (either 'g', 'git' of '+') is that
it does not provide an increasing version number, even for
fast-forwarding commits. Then it is not useful as a package version
number (deb or rpm). I've already seen deb packages with
version+git20061010.

The "either 'g',..." was something it that thread, but applies to the
current scheme.

Side note for side note.

This should be obvious to people who know git, but the above
does not mean we can remove gXXXX part from the describe output,
becauses there could be infinite number of commits that are 256
commits away from v2.6.20-rc5 tag.  v2.6.20-rc5-256 alone does
not uniquely identify the commit 419dd83.
