As long as special options stay special and we make a rule not to allow
any subcommand to assign its own meaning to them, the git wrapper can
lookahead and reorder, when seeing a command line:

	git scripted-command --special

into

	git --special scripted-command

And that approach would work well for built-ins as well, I would
imagine.

There is one minor detail, though.  There could be an option-parameter
that is literally --special.  E.g.

	git grep -e --no-paginate

should not be reordered to

	git --no-paginate grep -e
