The su -l problem

[Scott Carmichael]

I sent an email a few weeks ago about the actions of su -l and how it
messes up wtmp... I never got a reply, and the problem is still there. Is
anyone fixing this? It's quite annoying, since my 'ac' and 'last' logs are
also messed up because of it...

Thanks,
And here's an output of the problem, again:
