Description: Trigger speech start on final chunk of write
 When espeak is used with pulseaudio, the last part of a line or other chunk
 is not spoken because pa_stream_trigger needs to get called to start
 speech.  This is called if the buffer is full and writes are not
 progressing.  However nothing calls this for the last part of what's
 being spoken.  The contract for wave_write on the portaudio side
 seems to start the stream, so do the same on pulse.
 This patch takes advantage of the fact that calling pulse_free twice
 in a row with no write causes a trigger.  An alternative but larger
 change would be to refactor that code out of pulse_free.
