It's not exported to the environment, since `compgen' is a builtin command.
It doesn't really make sense for compgen to look in the temporary
environment anyway, since it's supposed to mimic, as much as is practical,
what a compspec constructed from a comparable set of completion options
would do when used for word completion. Word completion doesn't use the
temporary environment.
