Actually -n is implemented as if the user had answered 'n'
when he used the -i option - sure enough without prompting
the user.
$ echo n | cp -vi blah bar
cp: overwrite `bar'?
$ echo $?
0
BTW: it's similar with the mv command.
The texi page is a bit sparse about the exit value:
@exitstatus
Maybe it's worth adding a line about the exist status
when using -n or -i (together with answering 'n')?
Have a nice day,
