+ a trivial whitespace fix in 2/6.

I'll reproduce what it said for those who are reading from
sidelines:

    As noted there I can just run "make git", which I'd somehow managed to
    miss. So that complexity isn't needed.

    But Jeff King suggested a hack to just get you to the point of
    git.o. I don't need that right now, but that seems sensible, so I
    implemented it.

    At the start of this series I've got a patch to make "all" stop
    redundantly depending on "FUZZ_OBJS", which also helps with such
    "rebase -i --exec=..." use-cases.

I do not see much point in the goal, not quite.  You can do "make
git.o" and "make git" and you do not have to build unrelated things.

Isn't that already happening at the tip of 'master' (or 'maint'), or
am I missing something?
