So, based on the tinkering, it appears the the only safe way to get the
contents for a url is:

walk the log tree from the request revision till a copy/replace event,
then request the file from the original location [using any revision at
that point)

using the Ra instead of Client, I guess even better is to do:

checkpath with request url and revision
if it exists, simply cat using url/rev

if it doesn't exists, walk the log tree again, and fid the original
location. request the original location at the requested revision

My braind hurts.. :-)
