So what?  Putting bash in posix mode does not require bash to instantly
prohibit extensions.  POSIX intentionally allows for implementations to
provide extensions, and 'export -n' is one of bash's extensions.
There's no bug here, since leaving the extension always enabled does not
conflict with subset of behavior required by POSIX.
