4 issues with command arguments completion:
1) " " and "=false" shouldn't be proposed for argument without values (that is a regression introduced by the support of implicit true value).
2) arguments without values used to stop completion to operate. For example ls --resolve-expressions should complete to the argument separator " " if no more arguments can be added.
3) "=" character is not appended to argument that has a value (that is a regression introduced by the support of implicit true value).
4) Exception in read-attribute completing the node
read-attribute --node
