Right. That's what triggered my initial report, in which I confused that phenomenon for a failure of the 'unset' command to unset the variable.

  But it's not "permanently exported" as far as  I can see.

Sorry for the inexact use of language -- I simply meant that the global scope of the variable acquired the export flag, as opposed to the function-local scope.
