 Review comment:
   This suggestion for "idx" comes from a similar expression in UnshrinkingInputStream.java:
   
       60:        final int idx = addEntry(previousCode, character, MAX_TABLE_SIZE);
       61:        if (idx >= 0) {
       62:            isUsed[idx] = true;
       63:        }
       64:        return idx;
    
   The use of "idx" is slightly more common than "index" throughout the project. In this case, there's already a variable that has a similar use, so the system picked it up. Our system doesn't create a new name but it tries to choose the best looking candidate to make the code consistent with a minimal amount of change.
