[patch to servers/espeak]: translate [*] to space

[Chris Brannon <cmbrannon@xxxxxxxxxxx>]

When I type a character like left paren, the Espeak TTS server says 
"left `p1 paren".  Emacspeak sends "left[*]paren" to the tts_say procedure,
which translates [*] to `p1.  But the string `p1 isn't special to Espeak.
I'm guessing that Outloud renders it as a pause.
Here's my patch to translate [*] to space.
