[PATCH v2 8/9] log a detailed error (not usage()) when there are extra non-option arguments

[Laine Stump <laine@redhat.com>]

Telling the user "this bit is wrong" is more useful than telling them
"these are all the potential things that would be right; actual error
identification is left as an exercise for the reader".
