bug#22791: 25.0.91; Deleting dependency package and reinstalling overwrites custom file

bug#22791: 25.0.91; Deleting dependency package and reinstalling overwrites custom file

[Joost Kremers]

- Given the following init file:

```
(setq custom-file "~/.emacs.d/custom.el")

(require 'package)
;; (add-to-list 'package-archives '("melpa" . "http://melpa.org/packages/"))
(setq package-enable-at-startup nil)
(package-initialize)

(load custom-file)
```

- Customize some option (e.g., `fill-column') with `M-x
  customize-option'. (This is not an essential step, it just serves to
  illustrate the problem.)

- Install a package that has some dependency, e.g., ace-window, which
  has avy as a dependency.


    M-x package-install RET ace-window RET


- Close Emacs and do (from a shell):

    $ rm -rf ~/.emacs.d/elpa/avy-*

- Restart Emacs (this will give an error about not being able to load
  ace-window, because its dependency avy is not met.)

- Install avy:

    M-x package-install RET avy RET

At this point, the custom file ~/.emacs.d/custom.el is overwritten: the
custom setting for `fill-column' is gone.

The bug is dependent on `package-enable-at-startup' being set to nil and
`custom-file' being set. If either of these conditions isn't met, the
bug doesn't occur.

I can't try this recipe with Emacs 25, but with Emacs 26.3 and beyond
I'm unable to reproduce it.  The fill-column setting stays there after I
follow these steps.

Have you seen anything like this lately? Or is it possible that this was
fixed over the years?

I haven't seen anything like this happen again since I made the 
bug report. If it's not reproducible, then I guess it's safe to 
assume it was fixed somehow.

Ok, closing this bug.  Thanks.
