Not really. It used to be that way, but I improved that long ago.

Let's see how it is now... Ah, yes:
First we try to CWD there, to know if it's a dir or a file.
If it's a directory, then we're done.
If it's a file, then we use "LIST filename" to stat it (to get the size, ownership, \
whether it's a symlink etc.).
