util/bit53.lua @ 13769:5cc4a3e0335c 13.0

mod_admin_shell: Remove outdated help text (fixes #1898) The ! commands have been broken for some time, and we're not going to implement them right now. If we want fancier editing, we can now do that on the client side (with readline and stuff). Also removes mention of telnet!
