speakup-r functionality

[John Covici]

In my latest test, it still did not work.  I will send you a file to
test with.  I started  at the beginning of the file, went to line 25
and hit control and the cursor was at line 198.  Now it might work
differently with speech dispatcher, you probably should use a serial
synth to test.  Without the speakup-r empty line fix, it does work.
