So, we now have tldr, and navi, and mnemonic, and cheat, and maybe some more similar tools. But why don't we add these examples to the respective man pages? There's clearly a need for them.

I guess if you wanted you could make a new command that only prints the EXAMPLES section of a man page. It could turn out to be an improvement even since you get all the nice things that man provides like colours and consistent formatting for free.
