Me again, csetpruning

So for a temporary solution... I'll:
    o Copy my repo onto a backup so as to keep the history somewhere
    o Run csetprune to remove all delta's on binary files that are
      not the `head' delta.

I've been toying with 'bk prs' and its doc so as to generate the
list of keys to pass to csetprune (in order to prune just the history)

so far I have:  bk -r prs -hr+ -nd'$if(:ENC:=binary){:ROOTKEY:}'

which will fetch me all the deltas for binary files... how do
I specify that I want all deltas except the latest `HEAD' delta ?

Cheers,
                            -Tristan

Also stumbled on this:

I dont know about the site permissions but maybe I should (or
someone with permission should)... write this handy info in
as a workaround for other concerned googler's benefit ?
