Of course, idx is no longer a constant so declaring it as a variable
makes sense here.  But maybe just do it in the same patch because the
patch 1/1 doesn't make sense as a stand alone patch.

Also don't declare idx as an unsigned short.  It's better to declare it
as a int so it just works like a normal number and you don't have to
think about signedness bugs and wrapping and edge cases.
