Because I searched the git list and thats what I found. Also because
I'm familiar with what I want to do using git.

I'm not really worried about information loss. As long as I can still
get at the tags I'm happy. I'm not really planning on keeping this
repository after migrating the patches (well may be I'll keep it
around to submit the changes but I don't think the upstream project
would find them interesting anyway).

OK heres where I run into problems which I think may be due to
openSUSE 11.2s really old version of bzr (1.17). I was missing a 'cd'
in my example so I'm not sure if there is an implied one in the bzr
example. Either way its barfing on 'bzr checkout -rtag:<tagname>
tag-branch' and either refuses to work saying that tag-branch is not a
branch or crashes with I omit tag-branch.

except the list is subscriber only :( .

I'll give it a whirl when I've installed a newer version.

Yeah me too. I should probably bite the bullet and subscribe or import
the old and new tarballs and see what git can do with limited
information.
