Last summer i remember running some numbers on this in the tcl repo and IIRC 
the biggest collision was 10 or 11. 12 seemed to be the magic point at which 
all collisions disappear (IIRC).


It seems that in fossil the highest collision in fossil is 8 bytes long:
sqlite> select substr(uuid,0,8) as short, count(*) from blob group by short 
having count(short)>1;
b652b90|2sqlite> select uuid from blob where uuid glob 'b652b90*';

feedb652b9088b0d9e9cc8c2fb4c153443d72429d7c9  # some old/replaced C file

sqlite> select substr(uuid,0,9) as short, count(*) from blob group by short

blob group by short having count(short)>1;
sqlite> select substr(uuid,0,11) as short, count(*) from blob group by short 
having count(short)>1;
collisions start to become "common" at 7 bytes:
sqlite> select substr(uuid,0,7) as short, count(*) from blob group by short 
having count(short)>1;
