Thanks for the very useful tip! I will try to remember to use this for
any future testing.

That explains it, thanks! Maybe this could be added as an example to the
documentation for `git bundle`? People looking at `man git-bundle` hoping
to use it as one possible way to make a backup of a Git repository might
not realize right away that --all is the way to specify all refs, like
with `git log`.

Thanks again for your help, very welcome :-)
