Hi Adam,
This boils down to a 1 line (2 character) patch:

--- bash_completion.orig
+++ bash_completion
@@ -707,7 +707,7 @@ _init_completion()
         fi
     done
 
-    [[ $cword -eq 0 ]] && return 1
+    [[ $cword -le 0 ]] && return 1
     prev=${words[cword-1]}
 
     [[ ${split-} ]] && _split_longopt && split=true


If you are busy, I could apply this for you.  This ticket was originally posted for dports, but I requested that it be elevated to ports so FreeBSD would benefit too.
