I've considered it, and concluded that the post-patch 20 behavior is the
right thing.  If a variable assignment error occurs during execution of
a builtin, it should cause the builtin to return with a non-failure status
(unless you're running a non-interactive shell in posix mode, in which
case Posix says the whole shell should exit).

I do see what Gentoo is trying to do, and I'll try to devise a workaround
to accommodate both needs.
