so we load that GIT_TOPLEVEL_PREFIX_ENVIRONMENT prefix
first, such that we essentially copy it into GIT_PREFIX_ENVIRONMENT,
such that e.g. aliased commands will know about the superprefix, too.

ok, sounds reasonable to me; though I do not use this feature,
so my judgement is not as good.

Do we need a test for this behavior?

Thanks,
