My guess, from 908e531 (Add a "git-describe" command, 2005-12-24), is
that it's short for "git":

    IOW, with something like Junios current tree, I get:

        [torvalds@g5 git]$ git-describe parent
        refs/tags/v1.0.4-g2414721b

    ie the current head of my "parent" branch (ie Junio) is based on v1.0.4,
    but since it has a few commits on top of that, it has added the git hash
    of the thing to the end: "-g" + 8-char shorthand for the commit
    2414721b194453f058079d897d13c4e377f92dc6.

But I think only Linus (+cc) knows. :-)
