The easiest way to integrate them with the other components would be through combinators that convert block components to single-character components.

There should be a different component type for that purpose. It would still take one source and two sinks of the same type - one for the matching part of the input and the other for the consumed, but unmatched part - but it would not consume any input beyond what it needs to establish the match portion.

It would have to stop when either of the sources is exhausted. A merge component would also take two sources and one sink, but they'd all need to have the same type and it would run as long as either source provides more input. It's not too clear what combinators could apply to these component types.
