It still lacks a log message according to our conventions.

This only gives the header line of a commit log message, but the
"meat" is missing.  Here's a random example of a valid commit log
message (you can see more by typing "git log" from the shell prompt or
"C-x v L" inside Emacs):

    Implement missing functions for custom-icon widget

    * lisp/cus-edit.el (custom-icon-reset-saved, custom-icon-mark-to-save)
    (custom-icon-state-set-and-redraw, custom-icon-reset-standard)
    (custom-icon-mark-to-reset-standard): New functions.
    (custom-icon, custom-icon-extended-menu): Register and add them to the
    menu.  (Bug#66947)

See CONTRIBUTE for more information about our conventions in this
regard.

Our style is also to mention the interactive prompts in the doc
string:

    "Send LINE to all channels on all networks you are on.
  Interactively, prompt for the line of text to send."

> +(defun erc-cmd-AMSG (line)
> +  "Send LINE to all channels of the current network."

Same here.

> +(defun erc-cmd-GME (line)
> +  "Send LINE as an action to all channels on all networks you are on."

And here.

> +(defun erc-cmd-AME (line)
> +  "Send LINE as an action to all channels on the current network."

And here.

Thanks.
