ash: expand: Fix ghost fields with unquoted $@/$*

Upstream commit: Date: Fri, 23 Mar 2018 18:58:47 +0800 expand: Fix ghost fields with unquoted $@/$* You're right. The proper fix to this is to ensure that nulonly is not set in varvalue for $*. It should only be set for $@ when it's inside double quotes. In fact there is another bug while we're playing with $@/$*. When IFS is set to a non-whitespace character such as :, $* outside quotes won't remove empty fields as it should. This patch fixes both problems.

However, you're right that this is no longer the case. This patch will remove the persistence of the variable assignment. I have considered the exporting the variables during the function execution but have decided against it because: 1) It makes the code bigger. 2) dash has never done this in the past. 3) You cannot use this portably anyway.
