History
Evan Jones bc8b1ca320 remove the single backing string optimization 
This is a bit slower than using this optimization, but ensures this
version does not change garbage collection behavior. This does still
using a single []string for all the *string value pointers because
that is what text parsing already does. This makes the two behave
similarly.
