Pipe replacement testing
/segments takes multiple parameters, expands sprite identifiers (e.g., ) to sprite specifications (e.g.,  ), and returns them all as a single string delimited with +s.

(16,0 is the specification for "unknown identifier", and there's only one, so it's treating the input as a single sprite layer.)
