Since replication rules execute after `mysql_multi_update_prepare' returns we
delay to `break' in case this functions returns non-zero (some tables are not found) 
for to examine if there is an ignore rule for a not-found table. By doing that
it is guaranteed do/ignore replication rules logically preceed opening table routine.


sql/sql_parse.cc:
  BUG#15699. We delay to `break' in case of unexisted tables for multi-update.
  First it is checked whether an ignore rule for such a table exists.
  
  More to the fix:
  if (opt_readonly && ...' in two places got be idented because it were
  enclosed explicitly into corresponding `else' groups. For that 
  the preceding lines with `else' were changed in to be 
  `else 
   {'.
  This grouping is necessary to avoid any inattentive
  insertion in between of `else' and belonging to the else 
  `if (opt_readonly && ...' statement.
