Created attachment 386016 [details, diff] Add shortname -R for --changed-use option. Using emerge, --newuse has shortname -N, but --changed-use has no shortname. Let's change this; see attached patch. (I took a quick informal poll in #gentoo and -R won. I'm entirely indifferent as to the final shortname, though I personally like -H; that said, this patch uses -R. Easy enough to change.)
Created attachment 386410 [details, diff] Add shortname -U for --changed-use option. Upon advice from #gentoo-portage, apparently -U has been brought up as a suggestion in the past, and I happen to like it better than the alternatives. This is a fairly trivial patch (though I did check that it works locally); please let me know if any further changes are necessary.
Thanks, this is in git: https://github.com/gentoo/portage/commit/d55690aa3a1a9b4a78e87acd6ce179c17262966e
This is fixed in 2.2.14.
