USE=emacs in dev-vcs/git has little to no effect, except possible annoyances, that is because the Emacs Lisp libraries it ships with cannot be used. This is the content of "/usr/share/emacs/site-lisp/git/git.el": > (error "git.el no longer ships with git. It's recommended to > replace its use with Magit, or simply delete references to git.el > in your initialization file(s). See contrib/emacs/README in git's > sources (https://github.com/git/git/blob/master/contrib/emacs/README) > for suggested alternatives and for why this happened.

When removing "emacs" use flag we can instead rely on "optfeature" to inform the users about possibility of using magit - "app-emacs/magit" & print "einfo" that Emacs' "vc" can also be used.
Nice spot.
Right, we had already disabled the bundled elisp files for >=emacs-22 in 2007, see bug 194690. It was partially reenabled on user's request in bug 235393. This no longer makes sense, so let's just remove the emacs flag. IMHO no need for optfeature.
