Ah, I don't seem to have .git/logs at all.
We plan to upgrade to 1.5 when it's out, so I guess we'll just
have to wait.
Even with the git you have, you can probably just do a
git repo-config --global core.logallrefupdates true
and you'll have reflogs enabled for all of your repositories (well, at
least the ones that share that home directory and thus ~/.gitconfig)
