If we treat as special generic log file cleanup, then we should also
provide a subcommand to relocate unused logs elsewhere (for backup
purposes). But this is just silly. The removal and relocation of
logfiles can be done just fine with xargs or with a custom wrapper
script (for those on xargs-impaired OSes). We don't need to promote
every permutation of every command-line operation to a first-class


     +0 on --cleanlogs removing logs no longer in use by the DEST
        repos from SRC repos (that is what the option does, right)?
        This insures th at the subcommand never removes logs from SRC
        that it doesn't have a copy of in DEST. We don't strictly
        need this option at all.

     -1 on --cleanlogs removing that same set of logs from the DEST
        location. I'd like to guarantee that if you never removed
        logs by any external means, running 'svnadmin hotcopy
        --cleanlogs' routinely on your repository will a) keep your
        live repos log count as low as safely possible, and b)
        produces a set of backups from which every log file necessary
        for catastrophic recovery can be gleaned.

     -1 (no veto) on 'svnadmin cleanlogs'
