The current implementation of
PrefixInputseems to be inconsistent. It checks for the buffer being empty, but only after the prefix is taken, so trying to read with an zero-length buffer discards the prefix and it cannot be read any longer.Though the behavior can be fixed for the empty buffer case, I think it is better just to remove the check completely and add a "note" comment, since this is an internal mechanism used to parse compacts only and the buffer is always allocated properly.
