Currently, "C" asks before overwriting files.  rsync overwrites files
without asking.  Users who are used to having a prompt to prevent
accidental overwrites could be surprised of the new behaviour.  Maybe it
could be gentler to allow both cp and rsync implementations, and ask for
which to use on the first invocation (prominently indicating the new
overwrite behaviour), saving the setting for all later uses.

Which options should we give to rsync by default?  Maybe:

  -a --hard-links --partial --one-file-system

I'm not sure whether we should add --acls and/or --xattrs.

I think that's what --protect-args do.  Let's add it to the default
options.
