2008-09-22change string([]byte) to pass array, rather than &a[0],Russ Cox1-0/+9
to string convert. if the byte array has length 0, the computation of &a[0] throws an index bounds error. for fixed size arrays, this ends up invoking arrays2d unnecessarily, but it works. R=ken DELTA=304 (44 added, 28 deleted, 232 changed) OCL=15674 CL=15678
