[PATCH 0/5] "best effort" checkout

I consider the first one is not part of the series but a bugfix.

The remainder is to teach "git checkout" not to punt in the middle once it has started touching the work tree.

It does _not_ attempt to autorename a file whose name is NUL to something else. Partly because I personally think that sort of magic (or "a cute hack") makes the system unnecessarily complex and fragile while not adding much to the usability, but more importantly because I do not think we are ready to adopt that kind of complexity yet, before fixing more basic issue like this series addresses.
