Now you are talking about the behavior of ls, not of particular Hurd protocols.

What "ls foo" does is to readlink foo and then try to open the resulting
name (i.e. "").  Please show test cases that clearly exercise the
particular Hurd RPCs and clearly show the results.  You didn't show
e.g. `ls -l ""' in isolation, or `ls -Ll foo'.

You also haven't tested half the code, i.e. "ls -l foo/a" and the like.
