Seen on http://informationliberation.com/ - I cannot workout how to trigger
this myself, but the issue is when generating globalcode we use the existence
of globals to tell us that we've initialised "this" in the global scope.  But
if we have re-entered and no variables have been defined yet we re-add this,
resulting in us trying to increase the number of globals in the containing
scope, leading to badness.
