bug in cvs speakup

[Tyler Spivey]

hey. there is a minor bug in cvs speakup, i just got it a few days ago. the
double-say-line function (i believe it's called speakup_say_indennt)
is off by one space. if there is not indent, for example on the line:
this is a test
it will say "1 this is a test." i believe this is caused by a +1 in the
code, and it just seems weird. i believe the expected behaviour is to say
"0" for no indent.
