bug#73932: [PATCH] Add noconfirm to 'package-autoremove'

Hi folks,

Attached is a patch adding an optional NOCONFIRM argument to package-autoremove to skip user confirmation before removing packages.

I want to call package-autoremove in my init file to ensure there are no packages installed except those I configured explicitly via package-selected-packages.

For example, in one session I might install package XYZ interactively via the package menu to try it out. If I decide I like it, I’ll add it to package-selected-packages in my init file to keep it around. Otherwise, I want to make sure it gets blown away the next time I start Emacs.

This workflow is cumbersome in the current implementation of package-autoremove, which prompts the user before removing any packages. This patch adds an optional NOCONFIRM argument similar to what is implemented in package-install-selected-packages.

Please let me know if any changes are needed.

Thanks!

Thanks.  I'll let our package.el experts review and comment, but if
this is accepted, please add a NEWS entry for the new optional
behavior.

Also, would it make sense to turn NOCONFIRM on if the command is
invoked with a prefix argument?

Sounds good. Here is a patch with an attempt at a NEWS entry:

Sure, that might make sense. If we do that, should we do the same in package-install-selected-packages? It uses its NOCONFIRM argument in a similar way.
