Thanks for looking at it!

Good catch! I'll fix that in the next version.
Hmm, I think it would make sense to keep system_user() with his friends
current_user() and session_user().
But now that system_user() will not return a name anymore (but a text),
I think name.c is no longer the right place, what do you think? (If so,
where would you suggest?)

Oh right, I did not think about that, thanks for the suggestion.
I'll change this in the next version and simply skip the rest of the
test in case we get "peer authentication is not supported on this platform".
