To edit a message, clients send the edited message with a tag of `edit-message`. This tag has a required value of the `msgid` from the original message. The edited message MUST have the same command and first parameter as the original message, unless it is being changed into a multiline message (see below)
Servers MUST support editing `PRIVMSG`, `NOTICE`, `TAGMSG`, and `PART` messages, and MAY support editing any other type of message. Servers SHOULD enforce all checks that they normally would for that specific type of message (line length, color stripping, censoring, etc.) and return appropriate numerics if the message fails a check.

Servers MUST ensure that the user requesting deletion has sufficient privileges to delete the specified message. Servers MUST remove the content of the original message from all persistent history stores, and MAY replace the content with a generic deletion message if needed.
