I don't think we should be treating "git stash" as a special case here - 
commands like "git checkout" should not be removing untracked files 
unprompted either.

I think stopping and telling the user that the file would be overwritten 
as we do in other cases would be better.

I can see an argument for being able to opt-in to that for "git restore" 
and "git reset --hard" but that is a different problem to the one here.
