Enqueues a callback for calling upon commit. This is only necessary for line counting machines. Ragel will execute actions in real-time rather than after a complete match. This is a problem for entities that contain internal newlines, since there is a callback for each internal newline whether or not the end of the entity matches. This means that if, for example, the beginning of a string entity is matched, the text following is treated as code until the ending delimiter. If there is no ending delimiter (it was not actually a string entity), Ragel will jump back to the beginning of the string and reparse the text again. This means all the callbacks called were probably not accurate. To remedy this, any entity which needs an ending delimiter that may not appear will have its callbacks enqueued and then committed when the ending delimitter is reached. If that delimitter is not reached, the callbacks are never called. <dl compact><dt><b>Parameters:</b></dt><dd>
