+    Changing table order in the list can lead to different results. 
+    
+    Note also order of precedence of do/ignore rules (see code).  For

+    manual).
+
+    If no table in the list is marked "updating", then we always
+    return 0, because there is no reason to execute this statement on
+    slave if it updates nothing.  (Currently, this can only happen if
+    statement is a multi-delete (SQLCOM_DELETE_MULTI) and "tables" are
+    the tables in the FROM):
+
+    In the case of SQLCOM_DELETE_MULTI, there will be a second call to
+    tables_ok(), with tables having "updating==TRUE" (those after the
+    DELETE), so this second call will make the decision (because

+
+  NOTES
+    Here is the reason for this function.
+    We advise users who want to exclude a database 'db1' safely to do it
+    with replicate_wild_ignore_table='db1.%' instead of binlog_ignore_db or
+    replicate_ignore_db because the two lasts only check for the selected db,
+    which won't work in that case:
+    USE db2;
+    UPDATE db1.t SET ... #this will be replicated and should not
+    whereas replicate_wild_ignore_table will work in all cases.
+    With replicate_wild_ignore_table, we only check tables. When
+    one does 'DROP DATABASE db1', tables are not involved and the
+    statement will be replicated, while users could expect it would not (as it
+    rougly means 'DROP db1.first_table, DROP db1.second_table...').
+    In other words, we want to interpret 'db1.%' as "everything touching db1".
+    That is why we want to match 'db1' against 'db1.%' wild table rules.

-  Checks whether tables match some (wild_)do_table and (wild_)ignore_table

-  SYNOPSIS
-    tables_ok()
-    thd             thread (SQL slave thread normally)
-    tables          list of tables to check
-
-  NOTES
-    Note that changing the order of the tables in the list can lead to
-    different results. Note also the order of precedence of the do/ignore 
-    rules (see code below). For that reason, users should not set conflicting 
-    rules because they may get unpredicted results (precedence order is
-    explained in the manual).
-    If no table of the list is marked "updating" (so far this can only happen
-    if the statement is a multi-delete (SQLCOM_DELETE_MULTI) and the "tables"
-    is the tables in the FROM): then we always return 0, because there is no
-    reason we play this statement on this slave if it updates nothing. In the
-    case of SQLCOM_DELETE_MULTI, there will be a second call to tables_ok(),
-    with tables having "updating==TRUE" (those after the DELETE), so this
-    second call will make the decision (because
-    all_tables_not_ok() = !tables_ok(1st_list) && !tables_ok(2nd_list)).
-
-    Thought which arose from a question of a big customer "I want to include
-    all tables like "abc.%" except the "%.EFG"". This can't be done now. If we
-    supported Perl regexps we could do it with this pattern: /^abc\.(?!EFG)/
-    (I could not find an equivalent in the regex library MySQL uses).

-		Is tested with check_db_name() before calling this function.
-
-  NOTES
-    Here is the reason for this function.
-    We advise users who want to exclude a database 'db1' safely to do it
-    with replicate_wild_ignore_table='db1.%' instead of binlog_ignore_db or
-    replicate_ignore_db because the two lasts only check for the selected db,
-    which won't work in that case:
-    USE db2;
-    UPDATE db1.t SET ... #this will be replicated and should not
-    whereas replicate_wild_ignore_table will work in all cases.
-    With replicate_wild_ignore_table, we only check tables. When
-    one does 'DROP DATABASE db1', tables are not involved and the
-    statement will be replicated, while users could expect it would not (as it
-    rougly means 'DROP db1.first_table, DROP db1.second_table...').
-    In other words, we want to interpret 'db1.%' as "everything touching db1".
-    That is why we want to match 'db1' against 'db1.%' wild table rules.
