Escape i18n attributes as late as possible

[mfields]

The following code is found in multiple places in both Twenty Ten and Twenty Eleven:

printf( esc_attr__( 'Permalink to %s', 'textdomain' ), the_title_attribute( 'echo=0' ) )

While the value of the_title_attribute() is escaped before it is returned in this example, this code could be reworked to demonstrate the best practice of escaping as late as possible:

echo esc_attr( sprintf( __( 'Permalink to %s', 'textdomain' ), the_title_attribute( 'echo=0' ) ) )

Twenty Twelve is currently using code similar to the second example.
