Re: namref dicussion continued: [PATCH] export -r reference

[Dan Douglas]

Yeah I was just looking for this old script last night and just found it :)

If you scroll down to the output for "test 3" where "h" gets called
and passes a local "x" to a function that creates a reference to it
and exports the reference you can see that bash calls "x" unset in
both the first and second scope. As I recall we were discussing the
way exported locals interact between scopes at the time, not namerefs,
but I added the case for namerefs since I wasn't sure how this should
work. I should probably run it again with the current devel branch.

Even though bash doesn't yet support references for parameters like
ksh93, neither does mksh, which also shows differences from bash.
