comments are fixed as was suggested in reviews.

bugs/wls in cset's comments. The targetted BUG's or WL's identifier must be specified
the first in the comments. The referred bugs wls can be typed in same as the targeted
clickable format.
If the the target of the fix is a WL and there are some references to bugs
then the first found reference is regarded as "co-target" so that the bug's identifier
comes up on the subject line along with the WL's and commit mail will update
the bug page. The latter feature can be disarmed (if there is no need to update
the referred bug's page) with typing the first a pseudo-bug pattern (bug#0).

This paticular cset will generate subject line containing bug#0 (as it was the first
referred) whereas the old version would put in the subject line the last referred
pattern (e.g bug#2147483648).

  Problem: GROUP_CONCAT on a multi-byte column can truncate
  in the middle of a multibyte character when applying
  group_concat_max_len limit. It produces an invalid
  multi-byte character in the result string.
  
The second, easier version - reusing old "warning_for_row" flag,
instead of introducing of "result_is_full" - which was
added in the previous commit.
