        // allow for one additional split char (vs. the 18 unsplit chars in the three longs)
    // use extra two bits to represent:
        // 00 : final 6 (or fewer) chars (if 'a' is 0x01, zero could have special meaning)
        // 01 : not final 6 chars
        // 10 : color
        // 11 : unused, except as debugging sentinal? (could be -1 for easier test)
    // !!! the bit to end the word (last) is at the low bit for binary search
    // lookup first character in offset for quick start
        // offset is 27-entry table of bytes(?) that trims linear search to at most 21 entries ('d')
    // shift match into long; set bit 30 if it all doesn't fit
    // while longs don't match, march forward
        // if they do match, and bit 30 is set, advance match, clearing bit 30 if
        // final chars, and advance to next test
        // if they do match, and bit 30 is clear, get next long (color) and return it
    // stop at lookup of first char + 1
