Well, I never heard back from anyone about this. But I decided to pick
it up again. I decided to reformat it a little bit. So now it prints the
branch nickname, and reformats the output a little bit.

So now we have:
$ ./bzr --version
bzr (bazaar-ng) 0.7pre
  bzr checkout, revision 1491
  nick: bzr-jam-pending
  revid: john at arbash-meinel.com-20051228194754-27fd0b38f0b9a7f2

Since I worked on this, I'm actually looking into having setup.py
generate a snapshot of the version information, which I think will help
debug installed bzrlib. Also, I want this functionality for other
projects I have which are version controlled using bzr. I've done this
in the past for projects using baz/tla. Basically it is just a build
step which generates a version file.

These changes are available in my pending changes branch:
http://bzr.arbash-meinel.com/branches/bzr/jam-pending
The --version change is revno 1491.
