Jabber alert function should accept an optional second argument containing a
title of the message. The function mimic the default implementation of
jabber-alert-echo by showing the title if it is present and a message body
otherwise.
This commit fixes an error which is thrown when jabber receives a new notification:
(wrong-number-of-arguments (lambda (msg) (if (minibuffer-prompt) nil (message "%s" msg))) 2)
This reverts commit 29c78ce841 and all other fixes
that have been made afterwards.
The motivation is that use-package is seen by many as a replacement for
`require`. Is use-package always defer the loading of packages then is breaks
this use case, this does not respect POLA so even if it was making Spacemacs
loading faster (up to 3s faster on some startup on my machine) we just cannot
use it, it would be irresponsible. Spacemacs should be easy to use, loading
performance will come with time but it is not a priority.
