The change looks correct, thanks.

Hi,

according to the --help message and the manual of rm, the parameters
"-I" and "--interactive=once" should be absolutely identical. But when
you're deleting an unwritable file with parameter "-I", rm does not
prompt for this file. When you're using "--interactive=once" rm is
prompting.

As you can see rm prompts for the unwritable file "file1".

Now rm does not prompt for the unwritable file "file1".

This also happens if you're deleting "file1" only.

My system:
$ LC_ALL=C rm --version
