What you've found isn't a bug exactly, but certainly creates a situation
which is hard to explain and difficult to accommodate in the various actions
Subversion permits. Disallowing copies of not-up-to-date sources is one way
to help remedy the problem, but that would have to be implemented
server-side due to race conditions in commit ordering (for URL-to-URL
copies) and the natural delay between copy and commit when doing WC-based

We definitely don't want Subversion "pretending" that a history gap doesn't
exist, as this can cause it to return incorrect information in certain cases
(such as what happens when a *different* line of history is filling that gap
in the path namespace).
