Function claims_skill_call 

pub fn claims_skill_call(turn_skills: &mut Vec<String>, text: &str) -> bool

Whether text is the body of a skill the open turn holds a call for, consuming that claim.

A body belongs in the turn whose call loaded it: it is the same telling the call’s row already carries, and a turn of its own draws it a second time under the reader’s name. The claim is consumed so a later body for the same skill lands on the call after it, and a body no call holds opens a turn as it did before - nothing may be dropped.
