Bug#22877 replication character sets get out of

Browse Source 
sync using replicate-wild-ignore-table
Problem: changes in character set variables
before an action on an replication-ignored table
makes slave to forget new variable values.
Fix: initialize one_shot variables only when
4.1 -> 5.x replication is running.

It's ok to check thd->one_shot_set here:
The charsets in a MySQL 5.0 slave can change by both a binlogged
SET ONE_SHOT statement and the event-internal charset setting,
and these two ways to change charsets do not seems to work
together.
At least there seems to be problems in the rli cache for
charsets if we are using ONE_SHOT. Note that this is normally no
problem because either the >= 5.0 slave reads a 4.1 binlog (with
ONE_SHOT) *or* or 5.0 binlog (without ONE_SHOT) but never both."
