Adding a /usr/bin/-h command or whatever sounds like overkill to me. I wouldn't want that to be present on every system in the world. If you're maintaining a system that has extremely novice users on it, you're going to be the one selecting their shell for them, so you can just customize their shell. E.g. add a -h() function in /etc/bash.bashrc (or whatever your Linux distribution uses for that filename) which prints the message you'd like your users to see.
