Re: Start deprecating "git-command" in favor of "git command"

Well, we have a more serious issue, that is related, but has nothing to do

If you set an environment variable "diff.color=always", any script will 
get that behaviour, and not work the way it might expect.

My point being that this has nothing to do with "git-diff" vs "git diff", 
and everything to do with default configurations. If you don't want people 
to be able to change fixed behaviour, you'd need to have a way to disable 
it.

That's exactly why we have told people to use plumbing in their
scripts, and git-diff-tree does not look at diff.color.

Quite frankly, I think it's _easier_ to disable with "git xyzzy" than with 
"git-xyzzy", but hey, not a big deal. With "git xyzzy", we could add a 
generic flag like

	git - xyzzy

to make the rule be that no configurations (_including_ aliases) are 
allowed to override default behaviour, which is much harder with the 
"git-xyzzy" format (since then it's invariably a per-command thing).

But that would break existing scripts wouldn't it?
