It would be annoying to get this long message spamming the chat window.
Such error messages should describe what has gone wrong, but not give
any guidances, advices or directions; they belong elsewhere
(documentation, wiki, etc).
There are quite some problems with the way commands are explained:
* Interactivity - command arguments gets explained as if one is
following a guide ("insert this, enter that"). Better explain them
without any "guidance"; use present tense to describe commands.
* Duplicity - the purpose of the command is explained over and over
when arguments are being described.
* Separation - there is no need to divide required and optional
command arguments into their respective sections. Their amount did
not grow up that much for this to make sense.
* mute_command_help.html: i64 would be sufficient for developers, but
not end users. It does not stop anyone from specifying overflowing
integer, after all.
