message:
  Bug#36785: Wrong error message when group_concat() exceeds max length

  The problem is that when ER_CUT_VALUE_GROUP_CONCAT is elevated
  to a error, the message does not get updated with the number of
  cut lines when group_concat() exceeds max length.

  The solution is to modify the warning message to be more meaningful
  by giving the number of the line that was cut and to issue the warning
  for each line that is cut. This approach is inline with how other
  per-row truncated data warnings are issued avoids violating the warning
  internal interface.

mysql-test/suite/sys_vars/r/group_concat_max_len_func.result:
  Update result to reflect the new warning message
sql/share/errmsg.txt:
  Update warning message ER_CUT_VALUE_GROUP_CONCAT.
