I think there should at least be a truncation warning (or die)
for larger-than-4GB files on 32-bit. I don't know how common
they are for git-lfs users.
Perhaps using xsize_t in git-compat-util.h works for now:
len = xsize_t(file_stat.st_size);
(sorry, I haven't had much time to look at your other updates)
