Interactive dirs extension to rm

I want to not have to type rm -r when I remove a directory, and also I want it secure so I've aliased rm to coreutils rm -rI. The problem is that I get prompted even when removing files. This behavior is present in GNU as well. So I suggest adding a --interactive=dirs option. It will prompt only when at least one of the arguments is a directory.

Behaviour of rm -rI

user@machine> rm -rI foo
rm: remove 1 argument recursively?

It removes recursively no matter whether the argument is a file or directory

Requested behavior of rm -r --interactive=dirs

user@machine> rm -r --interactive=dirs foo
user@machine>

When no arguments are directories it doesn't remove recursively

user@machine> rm -r --interactive=dirs foo bar/
rm: remove 2 arguments recursively?

When at least one argument is a directory it produces the same behavior as rm -rI

The issue names no files or tests. Start by tracing the rm command's handling of -r, -I, and interactive options, then compare its behavior with the shell examples for file and directory arguments. Done means --interactive=dirs prompts only when at least one argument is a directory and matches the requested recursive behavior.
