To follow up on this problem (as I have it solved, or at least working), it seems you have to get rid of the information in the serial buffer so that the Serial.available bit won't interfere with things. I'm still not 100% though. I used Serial.end(), then Serial.begin(9600) to clear things out then reestablish the connection. Using Serial.flush() didn't work, which I thought was what that was for, but again I may be misunderstanding the mechanism. Anyway, I updated my code on GitHub, and the important bit is: 
  //Serial.flush(); did not work, used end/begin below
  Serial.end();
  Serial.begin(9600);
  //Serial.flush(); did not work, used end/begin below
  Serial.end();
  Serial.begin(9600);
This was instructive: https://forum.arduino.cc/t/clearing-serial-buffer-solved/227853
