Yes, it is a minor behavior modification but I can't think of another way to
do it (adding a separate function just for this little change feels bad) and I
guess this change will only affect a small amount of users.

BTW, I noticed the same flaw and need in the sftp_readdir function, and I
guess it may also be elsewhere once we start looking closer.
