Bug #2424 You cannot create a constraint if reference table has spaces in its name

Description:
If you try to create a foreign key constraint an the reference table has spaces in its name you get the error: [Explotación] ERROR 1005: Can't create table '.\test\maestro_de_cuentas.frm' (errno: 150)

How to repeat:
Create these tables:

CREATE TABLE `maestro_de_bancos` (
  `Banco` varchar(4) NOT NULL default '',
  `Descripción` varchar(50) default NULL,
  PRIMARY KEY  (`Banco`)
) TYPE=InnoDB; 

CREATE TABLE `maestro_de_cuentas` (
  `Id cuenta` int(11) auto_increment,
  `Banco` varchar(4) default NULL,
  `Sucursal` varchar(4) default NULL,
  `Dígito Control` char(2) default NULL,
  `Cuenta corriente` varchar(15) default NULL,
  PRIMARY KEY  (`Id cuenta`),
  KEY `cuenta` (`Banco`,`Sucursal`,`Cuenta corriente`),
  CONSTRAINT FOREIGN KEY (`Banco`) REFERENCES `maestro_de_bancos` (`Banco`) ON UPDATE CASCADE on delete restrict
) TYPE=InnoDB; 

rename `maestro_de_bancos` to `maestro de bancos`

issue a show create table `maestro_de_bancos` and you will get:

CREATE TABLE `maestro_de_cuentas` (
  `Id cuenta` int(11) NOT NULL auto_increment,
  `Banco` varchar(4) default NULL,
  `Sucursal` varchar(4) default NULL,
  `Dígito Control` char(2) default NULL,
  `Cuenta corriente` varchar(15) default NULL,
  PRIMARY KEY  (`Id cuenta`),
  KEY `cuenta` (`Banco`,`Sucursal`,`Cuenta corriente`),
  CONSTRAINT `0_60` FOREIGN KEY (`Banco`) REFERENCES `maestro de bancos` (`Banco`) ON UPDATE CASCADE
) TYPE=InnoDB; 

drop table `maestro_de_cuentas` and then submit the create table you have just obtained. It won't work despite it was the system you gave it to you.

Verified with 4.0.18/Linux.  Thank you.
