Replacing huge hidden selection when pasting text

[Alexandre Oberlin]

I have stopped hoping that the current maintainers of Emacs still have an ounce 
of common sense. How on Earth can it be possible (and quite easy) to allow 
replacing a huge hidden selection when pasting text without any warning ? I 
have lost large amounts of data with this incredibly stupid behavior. There 
isn't even a warning when saving a file which has shrunk a lot, like there once 
was. How can I DEFINITELY avoid overwriting an invisible selection in all 
versions of Emacs?
