Re: [PATCH 4/4] config: allow including config from repository blobs

No, I meant it explicitly to be about this single user hating it. Note
how the resulting commits are never pushed. It is purely a local

merge in further changes from upstream.

It also does allow "[include]ref = origin/meta:gitconfig" if you want to
live dangerously. I consider that a feature, because it lets the user
make the security tradeoff they deem appropriate.

While I do not think origin/meta:config is a sensible default, I actually
do think that:

	[include]
        	ref = meta:gitconfig
        [branch "meta"]
		remote = origin
        	merge = refs/heads/meta

makes some sense. The earlier example with the in-tree dev_tools/config in
the same line of history as the usual source material to keep track of
private changes ("this single user hating it") was not realistic as it
forbids the user from sharing the rest of the source once she decides to
fork the config preference.
