unknown f468b91f37 Fix for Bug#3904 "COUNT DISTINCT performance anomaly in 4.1"
The bug was caused by error in hash calculation function: it
always returned hash value for last field in a composite key, so 
for keys like (a text, b char(1)) we were always
getting bad hash values.
 


myisam/mi_unique.c:
  Fix for bug #3904:
  We should take into account existing hash value when calculating hash for
  next key in a composite unique index.
