Description

I have seen instances in support that ppl doing something like: (discord reformats the spacing so here is a screenshot)

Notice the 2 spaces between set and permnode? It results in setting an empty permission node with context server=permnode and world=true

Reproduction steps

1. Run any permission set command like this: /lp user ben permission set permnode true
2. And empty permission with weird context is set.

Expected behaviour

I suggest disabling the ability of setting an empty permission node.
