+Summary: gacutil throws System.IndexOutOfRangeException
+
+When you call `gacutil ""` or `gacutil -f ""`  or `gacutil "" -i` or any
+othe variant where an empty-string is passed to gacutil, I get a
+System.IndexOutOfRangeException.
+
+It is because of the IsSwitch method access the first charecter of the
+argument without checking it length before. I have provided a patch therfore.
