Message 267128 - Python tracker
For what it is worth, as a dedicated X11 user, *if* the target is already hilighted by the application I expect the replace behavior. But in my usage I never select the target myself, since that would replace my selection buffer. So in essence I'm seeing the "augment" behavior, but it's because I click to place the cursor where I want to paste, I don't select a target block to replace.
