Re: Concatenating transcript results

Stripping whitespace is something that almost every app that doesn't use
the API for dictation would need. To me this looks like an optional
feature, something which gets turned on based on a flag such as
"SpeechRecognition.autoWhiteSpace" that the developer would set if they
want it.. and as such it could be added in a future revision of the API if
we see developers asking for it.
