shave another 150K off of kc++, by using a 7-bit encoding for BB names
...
where we can. This shrinks kc++'s down to 3368K, with a VST record of:
Block ID #14 (VALUE_SYMTAB):
Num Instances: 2345
Total Size: 1.29508e+07b/1.61885e+06B/404713W
Average Size: 5522.73b/690.342B/172.585W

Tot/Avg SubBlocks: 0/0
Tot/Avg Abbrevs: 7035/3
Tot/Avg Records: 120924/51.5667
% Abbrev Recs: 100
Isn't it nice to be able to optimizer bc size without touching the reader? :)
