 I think the correct way to handle issue 730 is to move the dav
 checkout model into libsvn_client so all RA layers can benefit. In
 short, this model is:
 
    - fetch the top-level directory's props and a list of entries.
 
    - in an atomic fashion, create the .svn directory for that directory,
      populating its .svn/entries directories
 
      *** (if we are interrupted after this step, 'svn up' will see all
          missing children and fetch them, building out subtrees and all)
 
    - fetch each file in the entries list, loggily adding it to the
      working copy.
 
      *** (if we are interrupted after this step, 'svn up' will see
          perhaps some missing files, and all missing subdirs, and do
          the right thing)
 
    - for each subdirectory, do this whole process again (just down a
      directory level).
 
 I *think* this will work for us beautifully. What's more, I think
 that it can be basically accomplished using the RA get_dir and
 get_file interfaces.

I want a clarification - though I have a guess of the answer myself.

Can the ra_dav checkout model be generalized into update as well? With
this I mean that if an update results in the creation of a directory,
can that directory creation behave like the ra_dav checkout behaves -
first fetching the entries list and then fetching the entries - or is
the process there decidedly different. Since, now we know, that right
now, interrupting an update that creates a directory will result in
the very same problems that interrupting a checkout.

If the answer is that yes, it can - then that is what must be done
to update as well. If the answer is that no, it can't - then this
I can't see how this solution can work.
