bug#20594: master-branch broke my init

[Andreas Röhler]

Hi,

I'm using several Emacs, while .emacs is dispatching setups according to 
version.

After running an

emacs-master-20150509

any Emacs started with error - while loading the dispatched setup 
manually worked.

Finally detected in .emacs the reason:

;; Added by Package.el.  This must come before configurations of
;; installed packages.  Don't delete this line.  If you don't want it,
;; just comment it out by adding a semicolon to the start of the line.
;; You may delete these explanatory comments.
(package-initialize)

This is a bad thing. Please do not make Emacs write into the init-file 
behind the back of users.

Thanks,

Andreas

There's a thread on emacs-devel explaining the need for this. Other options
have been discussed there, a couple are under consideration (though it's
been quiet lately).

If you have suggestions, you're free to voice them here or there.

At least the user should be questioned yes-or-no-p once like "Write into 
your init...?"

Writing without notice IMO is a no-go.

Yes, I agree. There should either be a prompt or a notice about this.

In addition to that. A few days ago I added some logic to package.el
so that it won't add anything to your init file when it's not
necessary. That was after 20150509. It may or may not catch your
use-case.
Would you be willing to test if it works for you?

If you are, just (1) remove those lines, (2) rebuild today's master,
and (3) start emacs again.

Bug seems gone with build of today, thanks!

Please don't tell us which error you get, lest we'd get some idea of
how to fix it!
