Foo Mode enabled

Foo Mode enabled

[Eli Zaretskii]

If a minor mode is defined via define-minor-mode, then the status
message "FOO Mode enabled" is not displayed if toggling the mode
autoloads some package.

This happens because define-minor-mode has this fragment:

	 (if (called-interactively-p)
	     (progn
	       ,(if globalp `(customize-mark-as-set ',mode))
	       (unless (current-message)
		 (message ,(format "%s %%sabled" pretty-name)
			  (if ,mode "en" "dis")))))

I understand why this is done, but the latest changes that introduced
jka-cmpr-hook.el and rearranged the way auto-compression-mode is
loaded cause a minor misfeature due to this: if you start Emacs and
type "M-x auto-compression-mode RET", you will not see the message
telling you that Auto-Compression mode disabled".

I'm not sure what would be the best way to fix it.  It is easy to fix
this for jka-compr alone, but the questions is, should easy-mmode.el
do something differently in the above fragment (like perhaps not do
this for messages which announce loading of packages).

Here's an idea: don't suppress the mode state change message for
messages that were displayed by the execution of the minor mode
command itself.

This seems correct in general, and it could be done by calling
current-message atthe start of the function and comparing.
