When you're doing a commit, there is a single correct tree delta (a
reflection of the operations performed in the wc) and it is important
that it is transmitted and recorded accurately. But of course
svn_repos_dir_delta() is not used during a commit.

When you're talking to a working copy, the only thing that matters is
the end state. For an update or switch, the end state is easily defined
and any delta which gets you there is fine.

I guess the relevant question is in merge. If we are merging "delete
foo and replace foo with unrelated file" with "modify the contents of
foo", then we should get a directory-level conflict; my proposed change
would produce a file-level merge. So I guess we can throw out my idea.
