If I want to disable/enable viewing certain tags when I run vit I used to be able (vit 1.x) to pass through +tag -tag. In 2.x the argument parsing will give an error for -tag arguements that are not registered arguments for vit (i.e. it won't pass them through to task).

• vit next +tag
  • works as expected
• vit next -tag
  • error: vit: error: no such option: -t
  • workaround by explicitly turning off argument parsing: vit oldest -- -tag
