I thought they were already standardized ... But anyway, I was thinking
that this would generate *one* table listing all commands with their
tags. I was not thinking in putting the tag in each command's page:
I'm not sure that that would be generatable.

I can't say I'm terribly excited about this idea. I won't stop you if
you want to pursue it, but I'm not sure I see the value in a RETURN
VALUE section that says that the command returns the command name.
Maybe it would make sense to have that for the exceptional cases only?
