Hmmmm. Should it even get to this point? Temporary assignments preceding
function calls should go away, even in posix mode. The only thing that
could propagate in posix mode should be variable assignments directly
preceding `export',  but those should propagate back to the calling scope
and no further.

For instance, if you change the assignment to `v= export v', you get
the following output:

declare -A v

so certainly nothing propagated.

I realize it's not backwards-compatible, but propagating attributes from
export and readonly for variables that appear as assignments preceding
function calls looks like something that shouldn't be there in the first
place. What do you think?
