15 // compress names 6 chars per long (packed 5 bits/char )
16 // note: little advantage to splitting chars across longs, since 3 longs at 2 unused bits each
17 // allow for one additional split char (vs. the 18 unsplit chars in the three longs)
18 // use extra two bits to represent:
19 // 00 : final 6 (or fewer) chars (if 'a' is 0x01, zero could have special meaning)
20 // 01 : not final 6 chars
21 // 10 : color
22 // 11 : unused, except as debugging sentinal? (could be -1 for easier test)
23 // !!! the bit to end the word (last) is at the low bit for binary search
24 // lookup first character in offset for quick start
25 // offset is 27-entry table of bytes(?) that trims linear search to at most 21 entries ('d')
26 // shift match into long; set bit 30 if it all doesn't fit
27 // while longs don't match, march forward
28 // if they do match, and bit 30 is set, advance match, clearing bit 30 if
29 // final chars, and advance to next test
30 // if they do match, and bit 30 is clear, get next long (color) and return it
31 // stop at lookup of first char + 1
