Ah, that's another gotcha: you should configure Git to checkout "as
is".  See the instructions in nt/INSTALL, near its beginning.

If you run dos2unix or a similar program on these files, Git will
think they are modified.  So this is a bad idea.  Instead, remove the
Git repository, re-install Git as instructed in nt/INSTALL, then
re-clone the repository again.
