Function service_term 

fn service_term(name: &str) -> String

The filter term that selects one service, for a name picked out of the frame or map pane.

Always quoted, because tokens splits on whitespace and a service name is free to contain some. A name carrying a double quote has no equality spelling at all — the tokeniser toggles on one and there is no escape — so it degrades to a contains on the part before it, which is a true term rather than one that mis-parses into a different filter.
