Now it's more like 400.

Except that if the dotdot_found was what it seems to be, ".." would not be
added to the root directory only if ".." didn't already appear in the
listing for "/". Fortunately, the dotdot_found variable is now useless,
since handle_dirent() doesn't process "..", so your patch works.

I've applied a similar patch but removed dotdot_found to avoid confusion.
