This is not meant for application to the mainline.  It allows your
git to
refuse to create a blob whose name is "nul".

It's not just about "nul"; these won't work either: "aux", "prn", "con",
"com\d+", "lpt\d+", neither do "$one_of_these.$some_extension". And
all of
that regardless of the case!

Definitely, we don't ever want to have such special-casing somewhere
in git.

They _can_ be used by using the UNC notation:
    \\?\<drive letter>:\<path>\nul
Do you think we should special-case that, or simply fail?

Rhetoric question: What's so special about those files?

"foo/nul" is a file you don't have permissions to write to. Period. We
should fail the same way as if you had 'chmod a-w foo/nul foo', or as if
there's a bad sector on the disk. Junio's patch series is the way to go
(without 6/5, of course).
