Hello. This is feature request. 
I recently migrated to git portage tree and noticed that `equery changes` is broken (for example): 

equery changes gentoo-sources
!!! Fatal error: /usr/portage/sys-kernel/gentoo-sources/ChangeLog does not exist or is unreadable

Add '--debug' to global options for traceback.

Instead, works:
cd /usr/portage
git log -- sys-kernel/gentoo-sources

I posted my question on reddit first ( https://www.reddit.com/r/Gentoo/comments/49352m/changelog_in_git_tree/ ), where was found mentioned method. 
So, may be is it possible for equery to detect git tree in use and show appropriate information?
