+ CvPROTO returns the prototype as stored, which is not necessarily what
+ the interpreter should be using. Specifically, the interpreter assumes
+ that spaces have been stripped, which has been the case if the prototype
+ was added by toke.c, but is generally not the case if it was added elsewhere.
+ Since we can't enforce the spacelessness at assignment time, this routine
+ provides a temporary copy at parse time with spaces removed.
+ I<orig> is the start of the original buffer, I<len> is the length of the
+ prototype and will be updated when this returns.
