* firstLine ::= ("SM" | "SLM" | "NM" | "NLM") " " <lineToSay> [ "<" <voiceFile> | "<!" ]
* additionalLine ::= <skipped> " " <lineToSay> ( "<" <voiceFile> | "<!" )
*
* Say command comes in four variants: SM, SLM, NM and NLM.
* Note: In script files, they are usually written as *SM.
* The asterisk is ignored by the readLine function.
*
* Each of them plays a voice file (if present) and/or shows a message
* (if voice file not present or subtitles are enabled).
*
* The difference between versions starting with "S" and "N" is that
* the "N" version does not show talking animation.
*
* The "L" versions are "blocking", i.e. they wait for the previous say command to finish.
*
* If the line ends with "<!", it means the message continues to the next line.
* Next line usually has "SM" (or other variant) repeated, but it does not have to.
* Then we have the rest of the string to say (which is concatenated with the previous line)
* and possibly the voice file or "<!" again.
