are unaffected, that is underlying table names are not included

This fix doesn't solve SHOW CREATE TABLE issue.

Bug#31177: Server variables can't be set to their current values
Default values of variables were not subject to upper/lower bounds
and step, while setting variables was. Bounds and step are also
applied to defaults now; defaults are corrected quietly, values
given by the user are corrected, and a correction-warning is thrown
as needed. Lastly, very large values could wrap around, starting
from 0 again. They are bounded at the maximum value for the
respective data-type now if no lower maximum is specified in the
variable's definition.
client/mysql.cc:
correct maxima in options array
client/mysqltest.c:
adjust minimum for "sleep" option so default value is no longer
out of bounds.
include/m_string.h:
ullstr() - the unsigned brother of llstr()
include/my_getopt.h:
Flag if we bounded the value (that is, correct anything aside from
making value a multiple of block-size)
mysql-test/r/delayed.result:
We throw a warning now when we adjust out of range parameters.
mysql-test/r/index_merge.result:
We throw a warning now when we adjust out of range parameters.
mysql-test/r/innodb.result:

mysql-test/r/type_bit.result:
We throw a warning now when we adjust out of range parameters.
mysql-test/r/type_bit_innodb.result:
We throw a warning now when we adjust out of range parameters.
mysql-test/r/variables.result:
correct results: bounds and step apply to variables' default values, too
mysql-test/t/variables.test:
correct results: bounds and step apply to variables' default values, too
mysys/my_getopt.c:
- apply bounds/step to default values of variables (based on work by serg)
- print complaints about incorrect values for variables (truncation etc.,
by requestion of consulting)
- if no lower maximum is specified in variable definition, bound unsigned
values at their maximum to prevent wrap-around
- some calls to error_reporter had a \n, some didn't. remove \n from calls,
let reporter-function handle it, so the default reporter behaves like that
in mysqld
sql/mysql_priv.h:
correct RANGE_ALLOC_BLOCK_SIZE (cleared with monty)
sql/mysqld.cc:
correct maxima to correct data-type.
correct minima where higher than default.
correct range-alloc-block-size.
correct inno variables so GET_* corresponds to actual variable's type.
sql/set_var.cc:
When the new value for a variable is out of bounds, we'll send the
client a warning (but not if the value was simply not a multiple of
'blocksize'). sys_var_thd_ulong had this, sys_var_long_ptr_global
didn't; broken out and streamlined to avoid duplication of code.
