I agree the existing behaviour is undesirable for URL destinations.
The current libsvn_client implementation also suffers from a "check if
the destination URL exists" race which is probably an indicator that
the code doesn't belong in the library. I see no problem moving that
check into the client.
When the destination is a wc path it's less clear cut; the library
itself doesn't have a race, but there is still a race if the client
want's to check before calling the library function. Clients that
desire the existing behaviour currently get it without a race, moving
the check into the client would introduce a race. I suppose that
means we need to make the existing behaviour optional in the library.
Then the question arises, should it be optional for URLs as well?
These days I feel it was a mistake to make functions like
svn_client_move handle both URLs and wc paths, separate functions
would probably be better. I think a reasonable case can be made that
svn_path_is_url should only be used by the client and not by
