Here is what I wrote in What's cooking draft (which automatically gets copied to the merge log message and becomes part of release notes when a topic graduates) for this thing. Am I on the right track? The code internal to the recursive merge strategy was not fully prepared to see a path that is renamed to try overwriting another path that is only different in case on case insensitive systems. This does not matter in the current code, but will start to matter once the rename detection logic starts taking hints from nearby paths moving to some directory and moves a path that is otherwise not changed along with them.
