unknown 7a703d6ace Fix for BUG#8532. 
The problem was in that the code that analyses the applicability of the
QUICK_GROUP_MIN_MAX access method for DISTINC queries assumed that there
are no duplicate column references in the DISTINCT clause, and it added
non-exiting key parts for the duplicate column references. 

The solution adds a test to check whether the select list already contained
a field with the same name. If such field was already present, then it was
already decided to use its key part for index access. In this such case we
must skip the duplicate field instead of counting it as a new field.


mysql-test/r/group_min_max.result:
  Added test results for BUG#8532.
mysql-test/t/group_min_max.test:
  Added tests for BUG#8532.
