POSIX mandates that if the input of rm is a tty and it does not have write rights over a file/dir then it should ask for confirmation, in the same way that is done with the -i flag. To accomodate both things the code has been rearrenged a bit to have only one case instead of having two. Also, this rework adds the error message when a directory is removed without a -r flag.
