The Subversion 1.5 depth feature is a purely working-copy-local
concept. The server does not store a "recommended depth" for
directories. So it would certainly not be correct to have the script
you show end up checking out a non-infinite depth wc.

The key questions here is, if you do a wc-wc (or wc-repo) copy of a
non-infinite-depth wc path, should the commit just be
"add_directory(copyfrom=url-of-wc-directory)", or should it also fake
up some delete_entry calls to make the target of the copy "look like"
the wc version?

I'm not sure, but I'm leaning towards the current behavior being correct.
