No speech with `speechd-speak-function-feedback' when FEEDBACK is an expression

[Milan Zamazal]

Hi Alain,

I think this is done the way it is so that you could use any reporting
function in your feedback, not just only speechd-speak-report.  You can
use either string, which is passed to speechd-speak-report, or any sexp,
which is evaluated as it is.  In the latter case it's your
responsibility to send whatever and how you want to the output.

Your example doesn't work, because you just return some value and don't
deliver it to any output.  What you actually want is probably

  (speechd-speak-function-feedback helm-move-selection-common after
    (speechd-speak-report (my-get-helm-selection-string)))

Does it work for you?

And yes, speechd-speak-function-feedback docstring should be clearer
about that.

Regards,
Milan
