Well, while this "su -" behavior is a little unusual, I don't see
anything obviously wrong with it.  What behavior would you prefer?
Not logging the su sessions into wtmp at all (which I believe is the
case for most other implementations)?

The part of our su logging that really is questionable is that it adds
new entries to utmp (not wtmp, for which that is fine) for "su -"
sessions.  This makes you appear to be logged in twice.  Perhaps it
should replace the existing entry and restore it when the su session
ends.  This has been on TODO for a while now.
