Oh!  Thanks for that pointer --- it's very helpful.  I hadn't realized
that VFS for Git still requires a patched Git.

Separate from the "should" questions (in general I'm in favor of
unpatched Git being able to serve as a solid platform for both Scalar
and this kind of VFS use case), this context tells me that this is not
in fact a regression for VFS for Git users, so it's much appreciated.

Thanks,
Jonathan
