The check will also fail if someone happens to have two regular files
named "cur" and "new" next to a directory named "tmp", (which would then
be ignored). But I agree this seems very unlikely.

The rest of your analysis looks good to me. And it's nice to see how
simple the final patch is.

I had been waiting to apply the previous patch until I could test it on
a filesystem returning DT_UNKNOWN. But this one looks clean enough to
apply immediately.

One thing that would have made that easier would be a commit message,
(such as making a commit with "git commit" then using "git format-patch"
and "git send-email" to send it). But I'll go ahead and make one up.

Thanks again!
